The meditative contemplation of the Truth Reality of the Amitartha Sutra (Sutra of Innumerable Meanings) aims to illustrate the teaching of no-form, which is characterized by the emptiness of nature and characteristic. It also aims to teach all the bodhisattvas that they should skillfully observe the authenticity of all dharmas of the universe. Therefore, this sutra is not only one of meditative contemplation of the Truth Reality, but also one of bodhisattvas’ practice. As it attempts to lead all beings to attain in no instant anuttara-samyak-sambodhi and dwell permanently in ultimate bliss, its ultimate aim is to enable prompt enlightenment to the buddhahood. The thought of emptiness and wisdom featuring causal condition and the Middle Way of the Amitartha Sutra puts forth that the Truth Reality of the universe is not big or small, neither arises nor ceases, neither dwells nor moves, neither advances nor backsteps. The sentient beings are confused by the illusive conditioned phenomena and hence give rise to various unwholesome thoughts that eventually lead to immeasurable sufferings. The result of which is that they can never be liberated from the cycle of birth and death even after endless eons. The sutra teaches the beings to deeply observe all dharmas and see that they are by nature empty like the empty space and are not big or small, neither arises nor ceases, neither dwells nor moves, neither advances nor backsteps. By dwelling in the world of Truth Reality and developing the great bodhi mind, they can then alleviate the suffering of other beings so that they can also feel the ultimate bliss by dwelling in reality. This thesis tends to explore the thought of empty wisdom of conditioned Middle Way and the sequence of practice of the meditative contemplation, and illustrate the bodhisattva thought of the sutra. It will also study the development of the Truth Reality of the meditative contemplation, and the possible way of practice.
