Vaisampayana continued, "Saying this, the weeping king sat himself down upon the ground. Then a learned Brahmana, Saunaka by name versed in self-knowledge and skilled in the _Sankhya_ system of yoga, addressed the king, saying, 'Causes of grief by thousands, and causes of fear by hundreds, day after day, overwhelm the ignorant but not the wise. Surely, sensible men like thee never suffer themselves to be deluded by acts that are opposed to true knowledge, fraught with every kind of evil, and destructive of salvation. O king, in thee dwelleth that understanding furnished with the eight attributes which is said to be capable of providing against all evils and which resulteth from a study of the _Sruti (Vedas)_ and scriptures! And men like unto thee are never stupefied, on the accession of poverty or an affliction overtaking their friends, through bodily or mental uneasiness! Listen, I shall tell the _slokas_ which were chanted of old by the illustrious Janaka touching the subject of controlling the self! This world is afflicted with both bodily and mental suffering. Listen now to the means of allaying it as I indicate them both briefly and in detail. Disease, contact with painful things, toil and want of objects desired.--these are the four causes that induce bodily suffering. And as regards disease, it may be allayed by the application of medicine, while mental ailments are cured by seeking to forget them by _yoga_-meditation. For this reason, sensible physicians first seek to allay the mental sufferings of their patients by agreeable converse and the offer of desirable objects. And as a hot iron bar thrust into a jar maketh the water therein hot, even so doth mental grief bring on bodily agony. And as water quencheth fire, so doth true knowledge allay mental disquietude. And the mind attaining ease, the body findeth ease also. It seemeth that affection is the root of all mental sorrow. It is affection that maketh every creature miserable and bringeth on every kind of woe. Verily affection is the root of all misery and of all fear, of joy and grief of every kind of pain. From affection spring all purposes, and it is from affection that spring the love of worldly goods! Both of these (latter) are sources of evil, though the first (our purposes) is worse than the second. And as (a small portion of) fire thrust into the hollow of a tree consumeth the tree itself to its roots, even so affection, ever so little, destroyeth both virtue and profit. He cannot be regarded to have renounced the world who hath merely withdrawn from worldly possessions. He, however, who though in actual contact with the world regardeth its faults, may be said to have truly renounced the world. Freed from every evil passion, soul dependent on nothing with such a one hath truly renounced the world. Therefore, should no one seek to place his affections on either friends or the wealth he hath earned. And so should affection for one's own person be extinguished by knowledge.
