nirodhas tu loka-veda-vyāpāra-nyāsaḥ
nirodhaḥ—renunciation; tu—moreover; loka—of social custom; veda—and of the revealed scripture; vyāpāra—of the engagements; nyāsa—renunciation.
Such renunciation in devotional service means to give up all kinds of social customs and religious rituals governed by Vedic injunction.
In a verse in the Lalita-mādhava (5.2), Śrīla Rūpa Gosvāmī describes renunciation in devotional service:
ṛddhā siddhi-vraja-vijayitā satya-dharmā samādhir
brahmānando gurur api camatkārayaty eva tāvat
yāvat premṇāṁ madhu-ripu-vaśīkāra-siddhauṣadhīnāṁ
gandho ’py antaḥ-karaṇa-saraṇī-pānthatāṁ na prayāti
“Activities such as mystic trance, becoming one with the Supreme, and the religious principles of brahminism, such as speaking the truth and tolerance, have their own respective attractions, but when one becomes captivated by love of Kṛṣṇa, the Supreme Personality of Godhead, all attraction for mystic power, monistic pleasure, and mundane religious principles becomes insignificant.”
In other words, by discharging pure devotional service one attains the highest stage of love of Godhead and is freed from all other obligations, such as those mentioned in the karma-kāṇḍa, jñāna-kāṇḍa, and yoga-kāṇḍa sections of the Vedas. One who engages in pure devotional service has no desire to improve himself—except in the service of the Lord. In such devotional service there cannot be any worship of the impersonal or localized features of the Supreme Lord. The devotee simply performs activities that satisfy the Supreme Personality of Godhead and thus attains pure love for the Lord.
