What constitutes a true practice? It is contemplation on precious human birth, impermanence of life, and the other preliminaries. This discussion on the practice of the Four Dharma Seals is based on the teaching of Mipham Rinpoche, but overall, it is training in renunciation and bodhicitta, and gaining realization of emptiness of self through practices in Madhyamaka and Dzogchen.

We must try our utmost to cultivate these three qualities of mind. If at the end of our lives, we do not have renunciation and bodhicitta, nor realization of emptiness, and moreover cannot obtain a favorable rebirth in the three higher realms, the consequence of falling into the unfavorable realms is unthinkable.
