Buddha’s famous teaching or Sutra on emptiness, the profound nature of reality – the way things actually exist – contains the very essence of Buddha’s perfection of wisdom teachings. Through studying, contemplating and meditating on the Heart Sutra we can gain a perfect understanding of the nature of reality; we can overcome hindrances and difficulties in our daily life; and we can overcome the obstacles preventing our full enlightenment. A complete explanation of this Sutra can be found in Heart of Wisdom.
