While discharging devotional service in full Kṛṣṇa consciousness, one should not be miserly. He should not unnecessarily show that he has renounced this world. Actually, renunciation is not possible. If one renounces his palatial building and goes to a forest, there is actually no renunciation, for the palatial building is the property of the Supreme Personality of Godhead and the forest is also the property of the Supreme Personality of Godhead. If he changes from one property to another, that does not mean that he renounces; he was never the proprietor of either the palace or the forest. Renunciation necessitates renouncing the false understanding that one can lord it over material nature. When one renounces this false attitude and renounces the puffed-up position that he is also God, that is real renunciation. Otherwise, there is no meaning of renunciation. Rūpa Gosvāmī advises that if one renounces anything which could be applied in the service of the Lord and does not use it for that purpose, that is called phalgu-vairāgya, insufficient or false renunciation. Everything belongs to the Supreme Personality of Godhead; therefore everything can be engaged in the service of the Lord; nothing should be used for one's sense gratification. That is real renunciation. Nor should one unnecessarily increase the necessities of the body. We should be satisfied with whatever is offered and supplied by Kṛṣṇa without much personal endeavor. We should spend our time executing devotional service in Kṛṣṇa consciousness. That is the solution to the problem of life and death.
(Srimad Bhagavatam--------3:31:47--------purport).

"One who rejects things without knowledge of their relationship to Kṛṣṇa is incomplete in his renunciation." (Bhakti-rasāmṛta-sindhu 1.2.66) When the body is engaged in the service of the Lord, one should not consider the body material. Sometimes the spiritual body of the spiritual master is misunderstood. But Śrīla Rūpa Gosvāmī instructs, prāpañcikatayā buddhyā hari-sambandhi-vastunaḥ. The body fully engaged in Kṛṣṇa's service should not be neglected as material. One who does neglect it is false in his renunciation. If the body is not properly maintained, it falls down and dries up like an uprooted tree, from which flowers and fruit can no longer be obtained.
(Srimad Bhagavatam--------8:19:40--------purport).

The word markaṭa-vairāgya, indicating false renunciation, is very important in this verse. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura, in commenting on this word, points out that monkeys make an external show of renunciation by not accepting clothing and by living naked in the forest. In this way they consider themselves renunciants, but actually they are very busy enjoying sense gratification with dozens of female monkeys. Such renunciation is called markaṭa-vairāgya—the renunciation of a monkey.
(Sri Caitanya Caritamrta--------2:16:238---------purport).
