So by the grace of Lord Caitanya, who is not different from Kṛṣṇa . . . so Rūpa Gosvāmī detected this fact. When Rūpa Goswāmī first met Lord Caitanya at Prayāg, he offered his obeisances in this way:
- namo mahā-vadānyāya
- kṛṣṇa-prema-pradāya te
- kṛṣṇāya kṛṣṇa-caitanya-
- nāmine gaura-tviṣe namaḥ
- (CC Madhya 19.53)
He detected, "My dear Lord, You are Kṛṣṇa Himself. Now You have taken the form in the disguise of Caitanya, Śrī Kṛṣṇa Caitanya. You are chanting Hare Kṛṣṇa mantra. Your mission is to distribute kṛṣṇa-prema." Kṛṣṇa-prema. Kṛṣṇa . . . Caitanya Mahāprabhu's mission was to distribute Kṛṣṇa-prema. Premā pum-artho mahān (Caitanya-manjusa). He distributed love of God, how to love God. That is the highest perfection.
What is said here in the Bhagavad-gītā, manuṣyāṇāṁ sahareṣu kaścit yatati siddhaye . . . siddhaye. Siddhaye means how to obtain the perfection of life. The perfection of life is not dharma artha kāma mokṣa (SB 4.8.41, CC Adi 1.90). That is described in the beginning of Śrīmad-Bhāgavatam: dharmaḥ projjhita-atra kaitavaḥ (SB 1.1.2). Dharmaḥ projjhita-kaitavaḥ atra paramaḥ nirmatsarāṇāṁ.
In the beginning, introduction of Śrīmad-Bhāgavatam, the author, Vyāsadeva, says that all kinds of kaitavaḥ . . . kaitavaḥ. Śrīdhara Swami has commented upon it, kalaḥ niṣandi rūpa. Any religion which is seeking after some result of action . . . generally we perform religion, dharma-artha, we perform religion for getting some economic benefit, artha. And why artha is required? For kāma, dharma artha kāma.
