15. But the mind being guided by its intellectual powers, to the investigation of abstract truths, becomes an intelligent and intellectual principle, by its continued practice of thinking itself as such. (This is immaterial mind). 16. It is by virtue of the exertion of your manly powers and activities, and by force of constant habit and continued practice; that you can succeed to attain any thing, to which, you employ your mind with diligence. (Diligence overcomes all difficulties). 17. You can also be free from fears, and find your rest in your reliance in the sorrowless Being; provided you exercise your manly activities therein, and curb the proclivities of your mind by your intelligence. 18. It must be by the force of your intelligent mind, that you must lift up your deluded mind, which is drowned in the cares of this world. There is no other means that will help you to do so. 19. The mind only is capable of subduing the mind; for who can subdue a king unless he is a king himself? 20. Our minds are the boats, to lift us from the ocean of this world; where we are carried too far by its beating waves, and thrown into the eddies of despair, and where we are caught by the sharks of our greediness. 21. Let your own mind cut the net of the mind, which is ensnared in this world; and extricate your soul, by this wise policy, which is the only means of your liberation. (_i.e._ Set your mind to correct your mind). 22. Let the wise destroy the desires of their minds, and this will set them free from the bonds of ignorance. 23. Shun your desire for earthly enjoyments and forsake your knowledge of dualism; then get rid of your impressions of entity and non-entity, and be happy with the knowledge of one unity. 24. The thought of the unknowable, will remove the thoughts of knowables; this is equivalent to the destruction of desires, of the mind and ignorance also. 25. The unknown one of which we are unconscious by our knowledge, transcends all whatever is known to us by our consciousness. Our unconsciousness is our _nirvána_ or final extinction, while our consciousness is the cause of our woe. 26. It is by their own attention that men soon come to the knowledge of the knowables; but it is the unknowing or unconsciousness of these that is our _nirvána_, while our consciousness is the cause of our woe. (Want of self-consciousness, is want of pain. And perfect apathy is the perfection of solipsism). 27. Destroy O Ráma, whatever is desirable to your mind, and is the object of your affection; then knowing them as reduced to nothing, forsake your desires as seedless sprouts (which can never grow); and live content without the feelings of joy and grief.
