that is idle.  Be it happiness or be it misery, be it agreeable or be it disagreeable, what comes to one should be enjoyed or endured with an unconquered heart.  Every day a thousand occasions for sorrow, and hundred occasions for fear assail the man of ignorance and folly but not the man that is possessed of wisdom.  Sorrow can never touch the man that is possessed of intelligence, that has acquired wisdom, that is mindful of listening to the instructions of his betters, that is destitute of envy, and that is self-restrained.  Relying upon such an understanding, and protecting his heart (from the influences of desire and the passions), the man of wisdom should conduct himself here.  Indeed, sorrow is unable to touch him who is conversant with that Supreme Self from which everything springs and unto which everything disappears.[507] The very root of that for which grief, or heartburning, or sorrow is felt or for which one is impelled to exertion, should, even if it be a part of one’s body, be cast off.  That object, whatever it may be in respect of which the idea of meum is cherished, becomes a source of grief and heart-burning.  Whatever objects, amongst things that are desired, are cast off become sources of happiness.  The man that pursues objects of desire meets with destruction in course of the pursuit.  Neither the happiness that is derived from a gratification of the senses nor that great felicity which one may enjoy in heaven, approaches to even a sixteenth part of the felicity which arises from the destruction of all desires.  The acts of a former life, right or wrong, visit, in their consequences, the wise and the foolish, the brave and the timid.  It is even thus that joy and sorrow, the agreeable and the disagreeable, continually revolve (as on a wheel) among living creatures.  Relying upon such an understanding, the man of intelligence and wisdom lives at ease.  A person should disregard all his desires, and never allow his wrath to get the better of him.  This wrath springs in the heart and grows there into vigour and luxuriance.  This wrath that dwells in the bodies of men and is born in their minds, is spoken of by the wise as Death.  When a person succeeds in withdrawing all his desires like a tortoise withdrawing all its limbs, then his soul, which is self-luminous, succeeds in looking into itself.[508] That object, whatever it may be, in respect of which the idea of meum is cherished, becomes a source of grief and heart-burning.[509] When a person himself feels no fear, and is feared by no one, when he cherishes no desire and no aversion, he is then said to attain to the state of Brahma.  Casting off both truth and falsehood, grief and joy, fear and courage, the agreeable and the disagreeable, thou mayst become of tranquil soul.  When a person abstains from doing wrong to any creature, in thought, word, or deed, he is then said to attain to a state of Brahma.  True happiness is his who can cast off that thirst which is incapable of being cast off
