The Abhidhamma Pitaka is the most important and the most interesting of the three, containing as it does the profound philosophy of the Buddha’s Teaching in contrast to the illuminating and simpler discourses in the Sutta Pitaka.
In the Sutta Pitaka is found the conventional teaching (vohara desana) while in the Abhidhamma Pitaka is found the ultimate teaching (paramattha-desana).
To the wise, Abhidhamma is an indispensable guide; to the spiritually evolved, an intellectual treat; and to research scholars, food for thought. Consciousness is defined. Thoughts are analyzed and classified chiefly from an ethical standpoint. Mental states are enumerated. The composition of each type of consciousness is set forth in detail. How thoughts arise, is minutely described. Irrelevant problems that interest mankind but having no relation to one’s purification, are deliberately set aside.
Matter is summarily discussed; fundamental units of matter, properties of matter, sources of matter, relationship between mind and matter, are explained.
The Abhidhamma investigates mind and matter, the two composite factors of the so-called being, to help the understanding of things as they truly are, and a philosophy has been developed on those lines. Based on that philosophy, an ethical system has been evolved, to realize the ultimate goal, Nibbana.
The Abhidhamma Pitaka consists of seven books:
1. Dhammasangani (Classification of Dhammas)
2. Vibhanga (The book of Divisions)
3. Katha-Vatthu (Points of Controversy)
4. Puggala-Paññatti (Descriptions of Individuals)
5. Dhatu-Katha (Discussion with reference to elements)
6. Yamaka (The Book of Pairs)
7. Patthana (The Book of Relations)
In the Tipitaka one finds milk for the babe and meat for the strong, for the Buddha taught his doctrine both to the masses and to the intelligentsia. The sublime Dhamma enshrined in these sacred texts, deals with truths and facts, and is not concerned with theories and philosophies which may be accepted as profound truths today only to be thrown overboard tomorrow. The Buddha has presented us with no new astounding philosophical theories, nor did he venture to create any new material science. He explained to us what is within and without so far as it concerns our emancipation, as ultimately expounded a path of deliverance, which is unique. Incidentally, he has, however, forestalled many a modern scientist and philosopher.
Schopenhauer in his “World as Will and Idea” has presented the truth of suffering and its cause in a Western garb. Spinoza, though he denies not the existence of a permanent reality, asserts that all phenomenal existence is transitory. In his opinion sorrow is conquered “by finding an object of knowledge which is not transient, not ephemeral, but is immutable, permanent, everlasting.” Berkeley proved that the so-called indivisible atom is a metaphysical fiction. Hume, after a relentless analysis of the mind, concluded that consciousness consists of fleeting mental states. Bergson advocates the doctrine of change. Prof. James refers to a stream of consciousness.
The Buddha expounded these doctrines of transiency, (anicca), sorrow (dukkha), and no-soul (anatta) some 2500 years ago while he was sojourning in the valley of the Ganges.
It should be understood that the Buddha did not preach all that he knew. On one occasion while the Buddha was passing through a forest he took a handful of leaves and said: “O bhikkhus, what I have taught is comparable to the leaves in my hand. What I have not taught is comparable to the amount of leaves in the forest.”
He taught what he deemed was absolutely essential for one’s purification making no distinction between an esoteric and exoteric doctrine. He was characteristically silent on questions irrelevant to his noble mission.
Buddhism no doubt accords with science, but both should be treated as parallel teachings, since one deals mainly with material truths while the other confines itself to moral and spiritual truths. The subject matter of each is different.
The Dhamma he taught is not merely to be preserved in books, nor is it a subject to be studied from an historical or literary standpoint. On the contrary it is to be learnt and put into practice in the course of one’s daily life, for without practice one cannot appreciate the truth. The Dhamma is to be studied, and more to be practiced, and above all to be realized; immediate realization is its ultimate goal. As such the Dhamma is compared to a raft which is meant for the sole purpose of escaping from the ocean of birth and death (samsara).
Buddhism, therefore, cannot strictly be called a mere philosophy because it is not merely the “love of, inducing the search after, wisdom.” Buddhism may approximate a philosophy, but it is very much more comprehensive.
Philosophy deals mainly with knowledge and is not concerned with practice; whereas Buddhism lays special emphasis on practice and realization.
