Śrīmad-Bhāgavatam
[Canto 5, Ch. 5]
One should perform activities only for the benefit of the soul; any other activity should be given up. When a person is situated in this way, he is said to be desireless. Actually a living entity cannot be totally desireless, but when he desires the benefit of the soul and nothing else, he is said to be desireless.
Spiritual knowledge is  jñāna-vijñāna-samanvitam . When one is fully equipped with  jñāna  and  vijñāna , he is perfect.  Jñāna  means that one understands the Supreme Personality of Godhead,  Viṣṇu , to be the Supreme Being.  Vijñāna  refers to the activities that liberate one from the ignorance of material existence. As stated in  Śrīmad-Bhāgavatam  (2.9.31):  jñānam parama-guhyam me yad vijñāna-samanvitam . Knowledge of the Supreme Lord is very confidential, and the supreme knowledge by which one understands Him furthers the liberation of all living entities. This knowledge is  vijñāna . As confirmed in  Bhagavad-gītā  (4.9):
janma karma ca me divyam evaṁ yo vetti tattvataḥ tyaktvā dehaṁ punar janma naiti mām eti so 'rjuna
“One who knows the transcendental nature of My appearance and activities does not, upon leaving the body, take his birth again in this material world, but attains My eternal abode, O Arjuna.”
