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 Vairochanas posture are:

If we want to colour our mind with a virtuous motivation we need to clear away all our negative thoughts and distractions.

A further feature of Vairochanas 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.

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.
