CC Madhya 8.142
kalita-śyāmā-lalito rādhā-preyān vidhur jayati
akhila-rasa-amṛta-mūrtiḥ — the reservoir of all pleasure, in which exist all the mellows of devotional service, namely śānta, dāsya, sakhya, vātsalya and mādhurya; prasṛmara — spreading forth; ruci — by His bodily luster; ruddha — who has subjugated; tārakā — the gopī named Tārakā; pāliḥ — the gopī named Pāli; kalita — who has absorbed the minds of; śyāmā — the gopī named Śyāmā; lalitaḥ — and the gopī named Lalitā; rādhā-preyān — dearmost to Śrīmatī Rādhārāṇī; vidhuḥ — Kṛṣṇa, the Supreme Personality of Godhead; jayati — all glories to.
“ ‘Let Kṛṣṇa, the Supreme Personality of Godhead, be glorified! By virtue of His expanding attractive features, He subjugated the gopīs named Tārakā and Pāli and absorbed the minds of Śyāmā and Lalitā. He is the most attractive lover of Śrīmatī Rādhārāṇī and is the reservoir of pleasure for devotees in all transcendental mellows.’
Everyone has a particular transcendental mellow by which he loves and serves Kṛṣṇa. Kṛṣṇa is the most attractive feature for every kind of devotee. He is therefore called akhila-rasāmṛta-mūrti, the transcendental form of attraction for all kinds of devotees, whether the devotee be in the śānta-rasa, dāsya-rasa, sakhya-rasa, vātsalya-rasa or mādhurya-rasa.
This is the opening verse of the Bhakti-rasāmṛta-sindhu, by Śrīla Rūpa Gosvāmī.
