Balarāma means guru-tattva. Balarāma represents guru. Yasya prasādād bhagavat-prasādaḥ. If we want to understand Caitanya Mahāprabhu, if we want to understand Kṛṣṇa, then we must take shelter of Balarāma. Nāyam ātmā bala-hinena labhyaḥ. This bala-hinena labhyaḥ, this Vedic injunction, means “Without the mercy of Balarāma you cannot understand, you cannot realize your spiritual identification. So that Balarāma comes as Nityānanda Prabhu. Balarāma hailā nitāi. Therefore we must take shelter of Balarāma.

Lord Nityānanda Prabhu’s Āvirbhāva Appearance Day
Bhuvaneśvara, February 2, 1977
Prabhupāda: So today, the appearance day of Nityānanda Prabhu… Nityānanda Prabhu is Baladeva, Baladeva-tattva.
vrajendra-nandana yei, śacī-suta haila sei,
balarāma haila nitāi
“Who was formerly the son of Nanda Mahārāja, He has appeared as the son of Śacīdevi.” Caitanya Mahāprabhu’s mother’s name was Śacīdevi. So Kṛṣṇa… Kṛṣṇa is Śrī Caitanya Mahāprabhu, and Balarāma is Nityānanda Prabhu. Now…
vrajendra-nandana yei, śacī-suta haila sei,
balarāma haila nitāi
So Balarāma… In the Vedic literature it is said, nāyam ātmā bala-hinena labhyaḥ; na bahunā śrutena. So bala means strength. Sometimes some rascal philosophers, they take it that bala means bodily strength. They propagate this philosophy that “Unless you are bodily stout and strong, you cannot achieve spiritual salvation. You must be very strong and stout and eat meat and fight, and then you’ll get next spiritual birth” No. This bala, this strength, is different. This is spiritual strength.
