(Srila Prabhupada offering arotika to Kṛṣṇa-Balarāma, Vṛndāvana 1975)
"Balarāma is Nityānanda. Vrajendra-nandana yei, śacī-suta haila sei, balarāma ha-ila nitāi. This bala—Balarāma—comes with Śrī Caitanya Mahāprabhu, and both of Them are so merciful that in this age of Kali one may very easily take shelter of Their lotus feet. They come especially to deliver the fallen souls of this age. pāpī tāpī yata chila, hari-nāme uddhārila. Their weapon is saṅkīrtana, hari-nāma. Thus one should accept the sword of knowledge from Kṛṣṇa and be strong with the mercy of Balarāma. We are therefore worshiping Kṛṣṇa-Balarāma in Vṛndāvana. In the Muṇḍaka Upaniṣad (3.2.4) it is said:
nāyam ātmā bala-hīnena labhyo
na ca pramādāt tapaso vāpy aliṅgāt
etair upāyair yatate yas tu vidvāṁs
tasyaiṣa ātmā viśate brahma-dhāma
One cannot attain the goal of life without the mercy of Balarāma. Śrī Narottama dāsa Ṭhākura therefore says, nitāiyera karuṇā habe, vraje rādhā-kṛṣṇa pābe: when one receives the mercy of Balarāma, Nityānanda, one can attain the lotus feet of Rādhā and Kṛṣṇa very easily.
se sambandha nāhi yāra, bṛthā janma gela tāra,
vidyā-kule hi karibe tāra
If one has no connection with Nitāi, Balarāma, then even though one is a very learned scholar or jñānī or has taken birth in a very respectable family, these assets will not help him. We must therefore conquer the enemies of Kṛṣṇa consciousness with the strength received from Balarāma."
