The Heart Sutra,aka Prajna Paramita, is one of the most universal Buddhist chants. As the most concise Buddhist scripture, this summarizes the Buddha's teaching on the nature of existance, emptiness(or our true nature beyond ego) and the basis for compassion. It is a classic chant recited among all Buddhists. This is powerful chant, especially when played/chanted around the full moon, new moon and for uplifting the heart. This version is sung. According to Guru Rinpoche, the more beautifully performed chant creates greater merit or positive karmic benefits.
