This practice includes eloquent praises and mantra recitation to Chenrezig, the Buddha of Compassion, to help develop the mind of compassion, with teachings on the benefit of such practice by Lama Zopa Rinpoche.
“Your compassion is the source of all happiness, even the happiness of the animals and people that you meet in everyday life. Without compassion, there are personality/ego clashes and other problems: anger, jealousy, and many other things. Without compassion, life gets trapped in problems like a mouse trapped in a cage, an elephant drowning in mud, or a fly who flies into a spider's web and gets completely caught. Life gets completely caught up in problems and continues like that until you die – just like that fly. Therefore, compassion is the most important Dharma practice in life and the most important meditation.
"In order to develop great compassion, you need an understanding of the Buddha’s teachings on how to develop compassion. Thus, being able to recite by heart and meditate on the teachings alone is not enough in order to achieve realization. You also need to have realizations with the support of the Compassion Buddha’s blessing. This requires you to practice and do the meditation-recitation of the Compassion Buddha, Avalokiteshvara (Chenrezig).” – Lama Zopa Rinpoche
