The Great Compassion Mantra of Natural Wisdom is a powerful Mantra developed by Mahayana Buddhists. This Mantra is said to have the power to liberate all sentient creatures from the Hell of Suffering, delivering them from Ignorance. In this third and final volume in the series, Master Shanjian Dashi explores the Ten Heart Attributes of the Buddha Nature and gives detailed instruction on the practice of Mindfulness that complements the chanting of the Great Mantra. The Great Compassion Mantra is a verbal form of Dharana, a Sutra which uses syllables to transmit a powerful and effective transcendental message, creating a special state of consciousness. The transcendental message and the special state of consciousness set the conditions necessary for major changes in Attitudes, Intentions, and Actions. This awakens Benevolent Love, Compassion, and Gladness, engenders the Liberation of Wisdom, and facilitates the elimination of Suffering and Stress. The Mantra and the Commentary provide then the knowledge which leads to personal growth and the firm establishment of Wisdom, and can therefore be used to completely change the focus of one's own life or the lives of others who are open and receptive to what we can call Cosmic Consciousness.
