Twirling a flower, the Buddha revealed the mind-to-mind seal

Shakyamuni Buddha initiated Chan investigation when he held aloft a flower in the Vulture Peak Assembly to indicate the transmission of the subtle and wonderful mind seal Dharma door. At that time, Patriarch Mahakasyapa understood the intention of the Buddha, and smiled broadly. From then on, the mind seal Dharma door of the Buddhas and Patriarchs was transmitted. Actually, Patriarch Mahakasyapa was already over a hundred years old and because he vigorously practiced asceticism, he normally would not have smiled. On this occasion, his smile was an indication that he had just received the Buddha’s mind-to-mind seal.
