tad gaccha śreyase sarvaṃ mamaitad bhavatā kṛtam
yad vimuktiprado yogaḥ proktaḥ keśidhvajāvyayaḥ //

Kháńd́ikya replied to Keśidhwaja, and said, "The explanation which you have given me of the real nature of contemplative devotion has fulfilled all my wishes, and removed all impurity from my mind. The expression 'mine,' which I have been accustomed to use, is untruth, and cannot be otherwise declared by those who know what is to be known. The words 'I' and 'mine' constitute ignorance; but practice is influenced by ignorance. Supreme truth cannot be defined, for it is not to be explained by words. Depart therefore, Keśidhwaja; you have done all that is necessary for my real happiness, in teaching me contemplative devotion, the inexhaustible bestower of liberation from existence."
