ahaḿ hare tava pādaika-mūla-
dāsānudāso bhavitāsmi bhūyaḥ
manaḥ smaretāsu-pater guṇāḿs te
gṛṇīta vāk karma karotu kāyaḥ
O my Lord, O Supreme Personality of Godhead, will I again be able to be a servant of Your eternal servants who find shelter only at Your lotus feet? O Lord of my life, may I again become their servant so that my mind may always think of Your transcendental attributes, my words always glorify those attributes, and my body always engage in the loving service of Your Lordship?
This verse gives the sum and substance of devotional life. One must first become a servant of the servant of the servant of the Lord (dāsānudāsa). Śrī Caitanya Mahāprabhu advised, and He also showed by His own example, that a living entity should always desire to be a servant of the servant of the servant of Kṛṣṇa, the maintainer of the gopīs (gopī-bhartuḥ pada-kamalayor dāsa-dāsānudāsaḥ). This means that one must accept a spiritual master who comes in the disciplic succession and is a servant of the servant of the Lord. Under his direction, one must then engage one’s three properties, namely his body, mind and words. The body should be engaged in physical activity under the order of the master, the mind should think of Kṛṣṇa incessantly, and one’s words should be engaged in preaching the glories of the Lord. If one is thus engaged in the loving service of the Lord, one’s life is successful.
