The more we hear from realized souls, the more we make advancement in our devotional life. The more we advance in devotional life, the more we become detached from the material world. The more we become detached from the material world, as advised by Lord Caitanya Mahāprabhu, the more we increase in attachment for the Supreme Personality of Godhead. Therefore, a devotee who actually wants to make progress in devotional service and go back home, back to Godhead, must lose interest in sense enjoyment and associating with persons who are after money and sense gratification.

Plain living and high thinking are recommended for a devotee. He should accept only so much as he needs to keep the material body fit for the execution of devotional service. He should not eat or sleep more than is required. Simply eating for living, and not living for eating, and sleeping only six to seven hours a day are principles to be followed by devotees. As long as the body is there it is subjected to the influence of climatic changes, disease and natural disturbances, the threefold miseries of material existence. We cannot avoid them.

The purport is that one cannot live outside the society of devotees; one must live in the association of devotees, where there is constant chanting and hearing of the glories of the Lord. The Kṛṣṇa consciousness movement is started for this purpose, so that hundreds of ISKCON centers may give people a chance to hear and chant, to accept the spiritual master and to disassociate themselves from persons who are materially interested, for in this way one can make solid advancement in going back home, back to Godhead.

One should take shelter of a pure devotee, who has nothing to do with this material world but is simply engaged in devotional service. By serving him only, one can transcend the qualitative material condition. In this verse it is recommended (yogeśvara-upāsanayā) that one serve the lotus feet of the topmost yogī, or the devotee. To serve the topmost devotee means to hear from him about the glories of the Supreme Personality of Godhead.

Everyone in human society is engaged for the ultimate benefit of life, but persons who are in the bodily conception cannot achieve the ultimate goal, nor can they understand what it is. When one finds out the supreme goal of life, he naturally becomes detached from the bodily concept

By association with devotees, dirty things within the heart of a materialistic man are gradually washed away by the grace of the Supreme Personality of Godhead. As silver becomes shiny by being polished, the heart of a materialistic person is cleansed of lusty desires by the good association of devotees. Actually the living being has no connection with this material enjoyment nor with lusty desires.

Hearing discussions among the devotees is the only means to receive the powerful message of the Supreme Personality of Godhead. For instance, Bhagavad-gītā has been well known all over the world for a very long time, especially in the Western world, but because the subject matter was not discussed by devotees, there was no effect. Not a single person in the West became Kṛṣṇa conscious before the Kṛṣṇa consciousness movement was founded. But when the same Bhagavad-gītā was presented as it is through the disciplic succession, the effect of spiritual realization was immediately manifested.

Mahārāja Pṛthu was well conversant in transcendental science, yet he presented himself before the Kumāras as one ignorant of it. The idea is that even if a person is very exalted and knows everything, before his superior he should present questions.

Pṛthu Mahārāja’s talks before the Kumāras were very laudable because of so many qualifications. A speech should be composed of selected words, very sweet to hear, and appropriate to the situation. Such speech is called meaningful. All these good qualifications are present in Pṛthu Mahārāja’s speech because he is a perfect devotee.

The devotees are representatives of the Supreme Personality of Godhead, and to elevate the conditioned souls to their original consciousness, they travel all over the universes to enlighten the conditioned souls about Kṛṣṇa consciousness.
