MEDITATION POSTURE
When we practise meditation we need to have a comfortable seat and a good posture. The most important feature of the posture is to keep our back straight. To help us do this, if we are sitting on a cushion we make sure that the back of the cushion is slightly higher than the front, inclining our pelvis slightly forward. It is not necessary at first to sit cross-legged, but it is a good idea to become accustomed to sitting in the posture of Buddha Vairochana. If we cannot hold this posture we should sit in one which is as close to this as possible while remaining comfortable.

The seven features of Vairochana’s posture are:

1.)The legs are crossed in the vajra posture. This helps to reduce thoughts and feelings of desirous attachment.
2.)The right hand is placed in the left hand, palms upwards, with the tips of the thumbs slightly raised and gently touching. The hands are held about four fingers’ width below the navel. This helps us to develop good concentration. The right hand symbolizes method and the left hand symbolizes wisdom – the two together symbolize the union of method and wisdom. The two thumbs at the level of the navel symbolize the blazing of inner fire.
3.)The back is straight but not tense. This helps us to develop and maintain a clear mind, and it allows the subtle energy winds to flow freely.
4.)The lips and teeth are held as usual, but the tongue touches against the back of the upper teeth. This prevents excessive salivation while also preventing our mouth from becoming too dry.
5.)The head is tipped a little forward with the chin slightly tucked in so that the eyes are cast down. This helps prevent mental excitement.
6.)The eyes are neither wide open nor completely closed, but remain half open and gaze down along the line of the nose. If the eyes are wide open we are likely to develop mental excitement and if they are closed we are likely to develop mental sinking.
7.)The shoulders are level and the elbows are held slightly away from the sides to let air circulate.
A further feature of Vairochana’s posture is the preliminary breathing meditation, which prepares our mind for developing a good motivation. When we sit down to meditate our mind is usually full of disturbing thoughts, and we cannot immediately convert such a state of mind into the virtuous one we need as our motivation. A negative, disturbed state of mind is like pitch-black cloth. We cannot dye pitch-black cloth any other colour unless we first remove all the black dye and make the cloth white again. In the same way, if we want to colour our mind with a virtuous motivation we need to clear away all our negative thoughts and distractions. We can accomplish this temporarily by practising breathing meditation.

BREATHING MEDITATION

When we have settled down comfortably on our meditation seat we begin by becoming aware of the thoughts and distractions that are arising in our mind. Then we gently turn our attention to our breath, letting its rhythm remain normal. As we breathe out we imagine that we are breathing away all disturbing thoughts and distractions in the form of black smoke that vanishes in space. As we breathe in we imagine that we are breathing in all the blessings and inspiration of the holy beings in the form of white light that enters our body and absorbs into our heart. We maintain this visualization single-pointedly with each inhalation and exhalation for twenty-one rounds, or until our mind has become peaceful and alert. If we concentrate on our breathing in this way, negative thoughts and distractions will temporarily disappear because we cannot concentrate on more than one object at a time. At the conclusion of our breathing meditation we should think `Now I have received the blessings and inspiration of all the holy beings.’ At this stage our mind is like a clean white cloth which we can now colour with a virtuous motivation such as compassion or bodhichitta.

Generally, the purpose of breathing meditation is to calm the mind and develop inner peace. We can use breathing meditations alone or as a preliminary practice to reduce our distractions before engaging in a Lamrim meditation

A SIMPLE BREATHING MEDITATION

The first stage of meditation is to stop distractions and make our mind clearer and more lucid. This can be accomplished by practising a simple breathing meditation. We choose a quiet place to meditate and sit in a comfortable position. We can sit in the traditional cross-legged posture or in any other position that is comfortable. If we wish, we can sit in a chair. The most important thing is to keep our back straight to prevent our mind from becoming sluggish or sleepy.

We sit with our eyes partially closed and turn our attention to our breathing. We breathe naturally, preferably through the nostrils, without attempting to control our breath, and we try to become aware of the sensation of the breath as it enters and leaves the nostrils. This sensation is our object of meditation. We should try to concentrate on it to the exclusion of everything else.

At first, our mind will be very busy, and we might even feel that the meditation is making our mind busier; but in reality we are just becoming more aware of how busy our mind actually is. There will be a great temptation to follow the different thoughts as they arise, but we should resist this and remain focused single-pointedly on the sensation of the breath. If we discover that our mind has wandered and is following our thoughts, we should immediately return it to the breath. We should repeat this as many times as necessary until the mind settles on the breath.

BENEFITS OF MEDITATION

If we practise patiently in this way, gradually our distracting thoughts will subside and we will experience a sense of inner peace and relaxation. Our mind will feel lucid and spacious and we will feel refreshed. When the sea is rough, sediment is churned up and the water becomes murky, but when the wind dies down the mud gradually settles and the water becomes clear. In a similar way, when the otherwise incessant flow of our distracting thoughts is calmed through concentrating on the breath, our mind becomes unusually lucid and clear. We should stay with this state of mental calm for a while.

Even though breathing meditation is only a preliminary stage of meditation, it can be quite powerful. We can see from this practice that it is possible to experience inner peace and contentment just by controlling the mind, without having to depend at all upon external conditions.

When the turbulence of distracting thoughts subsides and our mind becomes still, a deep happiness and contentment naturally arises from within. This feeling of contentment and well-being helps us to cope with the busyness and difficulties of daily life. So much of the stress and tension we normally experience comes from our mind, and many of the problems we experience, including ill health, are caused or aggravated by this stress.

Just by doing breathing meditation for ten or fifteen minutes each day, we will be able to reduce this stress. We will experience a calm, spacious feeling in the mind, and many of our usual problems will fall away. Difficult situations will become easier to deal with, we will naturally feel warm and well disposed towards other people, and our relationships with others will gradually improve.

Another method of meditation is mindfulness, which also comes from the Buddhist tradition. Conjuring mindfulness is essential in overcoming suffering and understanding natural wisdom. It is all about acknowledging reality by letting the mind wander, accepting any thoughts that come up, and understanding the present. For instance, if you opened that Mira window when you weren't supposed to or fuzed a hostage you'd briefly reflect on it during the meditation, accept that is what occurred and that there is nothing you can do to change it aside from learning from your error.

The practice is done by sitting with eyes close, crossed legs, the back straight, and attention placed on breathing in and out. For the period of meditation the individual focuses on his or her breathing, and when wandering thoughts emerge, one returns to focusing on the object of meditation, breathing. Research has found that a regimen of mindfulness can reduce anxiety, depression, and perceived distress.

Taoist Meditation emphasizes living in harmony with Nature, or Tao, and it’s main text is the Tao Te Ching, dating back to 6th century B.C. Later on some lineages of Taoism were also influenced by Buddhist meditation practices brought from India, especially towards the 8th century C.E..

The chief characteristic of this type of meditation is the generation, transformation, and circulation of inner energy. The purpose is to quieten the body and mind, unify body and spirit, find inner peace, and harmonize with the Tao. Some styles of Taoist Meditation are specifically focused on improving health and giving longevity.

There are several different types of Taoist meditation, and they are sometimes classified in three: “insight”, “concentrative”, and “visualization”. Here is a brief overview:

Emptiness meditation — to sit quietly and empty oneself of all mental images (thoughts, feelings, and so on), to “forget about everything”, in order to experience inner quiet and emptiness. In this state, vital force and “spirit” is collected and replenished. This is similar to the Confucius discipline of “heart-mind fasting”, and it is regarded as “the natural way”. One simply allows all thoughts and sensations arise and fall by themselves, without engaging with or “following” any of them. If this is found to be too hard and “uninteresting”, the student is instructed with other types of meditation, such as visualization and Qigong
Breathing meditation (Zhuanqi) — to focus on the breath, or “unite mind and qi”. The instruction is “focus your vital breath until it is supremely soft”. Sometimes this is done by simply quietly observing the breath (similar to Mindfulness Meditation in Buddhism); in other traditions it is by following certain patterns of exhalation and inhalation, so that one becomes directly aware of the “dynamisms of Heaven and Earth” through ascending and descending breath (a type of Qigong, similar to Pranayama in Yoga).
Neiguan (“inner observation; inner vision”) — visualizing inside one’s body and mind, including the organs, “inner deities”, qi (vital force) movements, and thought processes. It’s a process of acquainting oneself with the wisdom of nature in your body. There are particular instructions for following this practice, and a good book or a teacher is required.
