(41) To the pure of heart come also a quiet spirit, one-pointed thought, the victory over sensuality, and fitness to behold the Soul.

(5) By truthfulness, indeed, by penance, right knowledge, and abstinence must that Self be gained; the Self whom spotless anchorites gain is pure, and like a light within the body.

(9) In the highest golden sheath there is the Brahman without passions and without parts. That is pure, that is the light of lights, that is it which they know who know the Self.

(7) Along with it, a dull red light from the Preta-loka, coming side by side with the Light of Wisdom, will also shine upon thee. Act so that thou shalt not be fond of it. Abandon attachment [and] weakness [for it].

(9) O nobly-born, along with the radiances of Wisdom, the impure illusory lights of the Six Lokas will also come to shine. If it be asked, 'What are they?' [they are] a dull white light from the devas, a dull green light from the asuras, a dull yellow light from human beings, a dull blue light from the brutes, a dull reddish light from the pretas, and a dull smoke-coloured light from Hell. These six thus will come to shine, along with the six radiances of Wisdom; whereupon, be not afraid of nor be attracted towards any, but allow thyself to rest in the non-thought condition.

(89) Those whose mind is well grounded in the (seven) elements of knowledge, who without clinging to anything, rejoice in freedom from attachment, whose appetites have been conquered, and who are full of light, are free (even) in this world.
