Medhātithi’s commentary (manubhāṣya):
Disturbance of the mind caused by pleasure and pain, and appearing in the forms of joy and sorrow, should be got rid of in the following manner. [He shall cultivate the following idea]—‘When such and such a person does anything pleasing to me, it is the result of some good act that I may have done in the past; and the doer of the act has not done it. through any feelings of affection towards me; in fact he could not do anything inimical to me; and when some one does what is disagreeable to me, there also what is the source of my pain is only my own evil act this is what he shall ponder over while practising meditation; so that he does not feel any attraction towards the man who does what is agreeable to him, nor any repulsion towards one who does what is disagreeable to him.

By doing thus ‘he reaches the eternal Brahman’, directly, and has not got to pass through the intervening stages of the Luminous Path and so forth.

The presence of the epithet ‘eternal’ implies that the man does not return to the cycle of births and deaths.—(79)
