Chapter 1 Samanvaya Adhyaya, Section 1 Jijnasadhikaranam, Topic 1: The enquiry into Brahman and its prerequisites, Verse 1 (1:1:1:1):
Now, therefore, the enquiry into Brahman.
Atha: now, then, afterwards; Atah: therefore; Brahmajijnasa: a desire for the knowledge of Brahman (the enquiry into the real nature of Brahman).
Sutra literally means a string. It serves the purpose of stringing together the flowers of the Vedanta passages. The word ‘atha’ is not used to introduce a new subject that is going to be taken up. The enquirer should be endowed with certain spiritual requisites or qualifications. Then only the enquiry is possible. Atha, after the attainment of certain preliminary qualifications such as the four means of salvation:
Only those who have got an earnest desire for the knowledge of Brahman only are fit for the study of Vedanta philosophy or the Brahma Sutras. Even without possessing the know ledge of karmakanda, which deals with religious ceremonies or sacrifices, a desire for attaining the knowledge of Brahman will arise direct from the study of the shrutis. The enquiry of Brahman does not depend on the performance of any acts.
You must know and realize the eternal Brahman. Then only you will attain eternal bliss, freedom, perfection and immortality. You must have certain preliminary qualifications for your search. Why should you enquire about Brahman? Because the fruits obtained by sacrificesetc., are ephemeral, whereas the knowledge of Brahman is eternal. Life on this earth and the life in heaven which you will attain on account of your virtuous deeds are transient. If you know Brahman, you will enjoy everlasting bliss and immortality. That is the reason why you must start the quest of Brahman or the Truth or the Ultimate Reality.
A time comes when a person becomes indifferent to karmas. He knows that karmas cannot give him everlasting, unalloyed happiness which is not mixed with pain, sorrow and fear. Therefore, naturally a desire arises in him for the knowledge of Brahman or the all-pervading, eternal soul which is above karmas, which is the source of eternal happiness.
Charvakas or Lokayatikas, followers of the materialistic philosophy, think that the body is the soul. Some think that the senses are the soul. Some others think that the mind is the soul. Some think that the intellect is the soul. Some think that the soul is a mere momentary idea. Some think that nothing exists in reality. Some think that there is a soul which is different from the body which is both agent and enjoyer of the fruits of action. Others hold that he is not a doer but is only an enjoyer. Some think that the individual soul is a part of the Supreme Soul. Vedantins maintain that the individual soul is identical with the Supreme Soul.
Different schools of philosophy hold different views. Therefore, it is necessary to examine the truth of things very carefully. Knowledge of Brahman destroys avidya or ignorance which is the root of all evil, or the seed of this formidable samsara or worldly life. Hence you must entertain the desire of knowing Brahman. Knowledge of Brahman leads to the attainment of the final emancipation. Hence an enquiry about Brahman through the study of the shrutis which treat of Brahman is worthwhile and should be undertaken.
