SB 3.31.47 purport.…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.

SB 3.31.48 purport–It is sometimes misunderstood that if one has to associate with persons engaged in devotional service, he will not be able to solve the economic problem. To answer this argument, it is described here that one has to associate with liberated persons not directly, physically, but by understanding, through philosophy and logic, the problems of life. It is stated here, samyag-darśanayā buddhyā: one has to see perfectly, and by intelligence and yogic practice one has to renounce this world. That renunciation can be achieved by the process recommended in the Second Chapter of the First Canto of Śrīmad-Bhāgavatam.

Nov 4 1975 letter....Please accept my blessings. I am in due receipt of your letter as I was leaving the temple to come here to Bombay. You have rightly said that the best way to associate with the spiritual master is to follow his instructions. There are two ways of associating, by vani and by vapu. Vani means words and vapu means physical presence. Physical presence is sometimes appreciable and sometimes not. Therefore we should take advantage of the vani, not the physical presence, because the vani continues to exist eternally. Bhagavad-gita for example is the vani of Lord Krishna. Although Krishna was personally present 5,000 years ago and is no longer present physically from the materialistic viewpoint, still Bhagavad-gita continues. So you have correctly concluded.

EK-4—When we feel separation from Kṛṣṇa or the spiritual master, we should just try to remember their words of instructions, and we will no longer feel that separation. Such association with Kṛṣṇa and the spiritual master should be association by vibration, not physical presence. That is real association. We put so much stress on seeing, but when Kṛṣṇa was present on this earth, so many people saw Him and did not realize that He is God; so what is the advantage of seeing? By seeing Kṛṣṇa, we will not understand Him, but by listening carefully to His teachings, we can come to the platform of understanding. We can touch Kṛṣṇa immediately by sound vibration; therefore we should give more stress to the sound vibration of Kṛṣṇa and of the spiritual master—then we’ll feel happy and won’t feel separation.
