This practice is part of Atisha's 7-Point Mind Training. Breath is what connects us to the world. When there is breath, there is this world, the illusion, the Maya. When breath stands still, the world disappears. In meditative silence, there is only pure consciousness. How this pure consciousness interacts with the world, that transaction should be of love and compassion. Sending and receiving love, compassion, positivity, joy, peace.
