It is good to start each practice session with emotional attunement and purification of the energy of the surrounding space. For this purpose there exists a wonderful technique, known as the
"Cross of Buddha". It is performed in the following way.
For the best performance of this exercise we should accept the so-called "student posture": we should sit down on the heels holding the spine straight, toes looking backwards and palms of hands resting upon the thighs. Then we send waves of our benevolence and love from the chest forward, saying mentally:
"May all beings have peace! May all beings be calm! May all beings feel bliss!" We produce each of these three states inside (in the chest) first and then radiate them forward. Then we repeat this to the right, to the left, backwards, up and down. This is a powerful technique that allows us to bring harmony to ourselves, to the energy of the surrounding space and to the living beings around us.
