Srimad-Bhagavatam

SB Canto 10.1 to 10.13

Everything should be engaged in the service of the Lord. Hṛṣīkeṇa hṛṣīkeśa-sevanaṁ bhaktir ucyate (CC Madhya 19.170) (Nārada-pañcarātra). Everything—the mind, the body and all the sense organs—should be engaged in Kṛṣṇa's service. This is to be learned from expert devotees like Nārada, Svayambhū and Śambhu. This is the process. We cannot manufacture our own way of understanding the Supreme Personality of Godhead, for it is not that everything one manufactures or concocts will lead to understanding God.

SB 10.10.38, Translation and Purport

Henceforward, may all our words describe Your pastimes, may our ears engage in aural reception of Your glories, may our hands, legs and other senses engage in actions pleasing to You, and may our minds always think of Your lotus feet. May our heads offer our obeisances to everything within this world, because all things are also Your different forms, and may our eyes see the forms of Vaiṣṇavas, who are nondifferent from You.

Here the process of understanding the Supreme Personality of Godhead is given. This process is bhakti.

śravaṇaṁ kīrtanaṁ viṣṇoḥ

smaraṇaṁ pāda-sevanam

arcanaṁ vandanaṁ dāsyaṁ

sakhyam ātma-nivedanam

(SB 7.5.23)

Everything should be engaged in the service of the Lord. Hṛṣīkeṇa hṛṣīkeśa-sevanaṁ bhaktir ucyate (CC Madhya 19.170) (Nārada-pañcarātra). Everything—the mind, the body and all the sense organs—should be engaged in Kṛṣṇa's service. This is to be learned from expert devotees like Nārada, Svayambhū and Śambhu. This is the process. We cannot manufacture our own way of understanding the Supreme Personality of Godhead, for it is not that everything one manufactures or concocts will lead to understanding God. Such a proposition—yata mata, tata patha—is foolish. Kṛṣṇa says, bhaktyāham ekayā grāhyaḥ: "Only by executing the activities of bhakti can one understand Me." (SB 11.14.21) This is called ānukūlyena kṛṣṇānuśīlanam (CC Madhya 19.167), remaining engaged favorably in the service of the Lord.
