What is the significance of studying the Buddhist way of practice? Recently, the term “Siddhartha Intent” has been heard among Tibetan Buddhists. It means that we should be aware of the purpose of the Buddha’s renouncing the worldly life, which was to transcend the suffering of affliction. The way that makes this possible was practice, or the method of observation called satipaṭṭhāna. The practice of satipaṭṭhāna was later called “cessation and observation.” I will consider the historical development of this cessation and observation that first appeared in India, then developed in China and was renovated to Chan (Jpn. Zen) Buddhism.
