59. [Sanskrit available] The nature of reality (the entity of Brahma), is real at all times, and the condition of the unreal world is unsubstantial for ever, and can never be otherwise or real, though it may? appear as such for a time. Why then sorrow for what is nil and unreal.

60. [Sanskrit available] I am not of this body nor was I in it, nor shall I remain in it; nor is it any thing, even at present, except a picture of the imagination. Why then lament at its loss.
