What should we "do" with the mind in meditation? Nothing. Just leave it, simply, as it is.
Sogyal RinpocheLooking at the world today, we might easily forget that the main purpose of our life - you could call it the heart of being human - is to be happy. All of us share the same wish, and the same right, to seek happiness and avoid suffering. Even following a spiritual path, or the religious life, is a quest for happiness.
Sogyal RinpocheDevotion {to the spiritual master} becomes the purest, quickest, and simplest way to realize the nature of our mind and all things. As we progress in it, the process reveals itself as wonderfully interdependent: We, from our side, try continually to generate devotion; the devotion we arouse itself generates glimpses of the nature of mind, and these glimpses only enhance and deepen our devotion to the master who is inspiring us. So in the end devotion springs out of wisdom: devotion and the living experience of the nature of mind becomes inseparable, and inspire one another.
