In many places devotional service has been compared to a creeper. One has to sow the seed of the devotional creeper, bhakti-latā, within his heart. As he regularly hears and chants, the seed will fructify and gradually grow into a mature plant and then produce the fruit of devotional service, namely love of Godhead, which the gardener (mālā-kāra) can then enjoy without impediments.
(Sri Caitanya Caritamrta-1:9:9-purport).

When Uddhava was fully absorbed in the transcendental ecstasy of love of God, he actually forgot all about the external world. The pure devotee lives constantly in the abode of the Supreme Lord, even in the present body, which apparently belongs to this world. The pure devotee is not exactly on the bodily plane, since he is absorbed in the transcendental thought of the Supreme. When Uddhava wanted to speak to Vidura, he came down from the abode of the Lord, Dvārakā, to the material plane of human beings. Even though a pure devotee is present on this mortal planet, he is here in relation to the Lord for engagement in transcendental loving service, and not for any material cause. A living entity can live either on the material plane or in the transcendental abode of the Lord, in accordance with his existential condition. The conditional changes of the living entity are explained in the Caitanya-caritāmṛta in the instructions given to Śrīla Rūpa Gosvāmī by Lord Śrī Caitanya: "The living entities all over the universes are enjoying the effects of the respective fruitive results of their own work, life after life. Out of all of them, some may be influenced by the association of pure devotees and thus get the chance to execute devotional service by attainment of taste. This taste is the seed of devotional service, and one who is fortunate enough to have received such a seed is advised to sow it in the core of his heart. As one cultivates a seed by pouring water to fructify it, the seed of devotional service sown in the heart of the devotee may be cultured by pouring water in the form of hearing and chanting of the holy name and pastimes of the Lord. The creeper of devotional service, so nourished, gradually grows, and the devotee, acting as a gardener, goes on pouring the water of constant hearing and chanting. The creeper of devotional service gradually grows so high that it passes through the entire material universe and enters into the spiritual sky, growing still higher and higher until it reaches the planet Goloka Vṛndāvana. The devotee-gardener is in touch with the abode of the Lord even from the material plane by dint of performing devotional service to the Lord simply by hearing and chanting. As a creeper takes shelter of another, stronger tree, similarly the creeper of devotional service, nourished by the devotee, takes shelter of the lotus feet of the Lord and thus becomes fixed. When the creeper is fixed, then the fruit of the creeper comes into existence, and the gardener who nourished it is able to enjoy this fruit of love, and his life becomes successful." That Uddhava attained this stage is evident from his dealings. He could simultaneously reach the supreme planet and still appear in this world.
(Srimad Bhagavatam-3:2:6-purport).

Simple negation, or giving up the company of materialistic persons, will not do. We must have engagements. Sometimes it is found that a person interested in spiritual advancement gives up the company of material society and goes to a secluded place as recommended for the yogīs especially, but that will also not help a person in spiritual advancement, for in many instances such yogīs also fall down. As far as jñānīs are concerned, generally they fall down without taking shelter of the lotus feet of the Lord. The impersonalists or the voidists can simply avoid the positive material association; they cannot remain fixed in transcendence without being engaged in devotional service. The beginning of devotional service is to hear about the glories of the Supreme Personality of Godhead. That is recommended in this verse: vinā harer guṇa-pīyūṣa-pānāt. One must drink the nectar of the glories of the Supreme Personality of Godhead, and this means that one must be always engaged in hearing and chanting the glories of the Lord. It is the prime method for advancing in spiritual life. Lord Caitanya Mahāprabhu also recommends this in the Caitanya-caritāmṛta. If one wants to make advancement in spiritual life, by great fortune he may meet a bona fide spiritual master and from him learn about Kṛṣṇa. By serving both the spiritual master and Kṛṣṇa he gets the seed of devotional service (bhakti-latā-bīja), and if he sows the seed within his heart and waters it by hearing and chanting, it grows into a luxuriant bhakti-latā, or bhakti creeper. The creeper is so strong that it penetrates the covering of the universe and reaches the spiritual world and continues to grow on and on until it reaches and takes shelter of the lotus feet of Kṛṣṇa, just as an ordinary creeper also grows on and on until it takes a solid shelter on a roof; then it very steadily grows and produces the required fruit. The real cause of the growing of such fruit, which is here called the nectar of hearing the glories of the Supreme Personality of Godhead, is to water the creeper of devotional service by hearing and chanting. 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.
