In the new edition, in addition to the “Golden Light Sutra” and “Double Sutra”, the “Heart Sutra”, “Sutra of Remembrance of the Three Jewels”, “Vajra Cutting Sutra” (Diamond Sutra) and “Sutra of the Immeasurable Exalted Life and Primordial Wisdom” appeared. (Amitayus Sutra). The sutras preserve the speech of Buddha Shakyamuni, recorded by his disciples. Since the sutras contain the words of the Buddha himself, reciting them becomes an act of spreading the Buddha's teachings in this world. In terms of its power, the impact of the sutra on those who hear, read or write it is comparable to meeting the Buddha in the flesh.
