Śrī-vigraha. This is yajana yājana. Śrī-vigraha. This is Śrī-vigraha, Kṛṣṇa's arcā-mūrti. Kṛṣṇa has taken, advented, as avatāra, arcā-avatāra. Arcā-avatāra means made of stone, wood, metal, jewel, or coloring, painting. There are eight kinds of arcā-avatāra. So Kṛṣṇa has consented to descend before us to accept our service in a manner which we can do. If Kṛṣṇa remains in His virāḍ-rūpa, then it will be very difficult to capture Him. Kṛṣṇa remains in virāḍ-rūpa, but He becomes arcā-vigraha, a small deity, so that everyone can worship Him at home. It does not take much time, it does not take much place. To make dress of Kṛṣṇa you can utilize little cloth. Kṛṣṇa is agreeable to accept your service. And offering? Patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati (BG 9.26). At any means you can worship Kṛṣṇa, and that is the business of brāhmaṇa and Vaiṣṇava.
Brāhmaṇa... Brahma jānāti. One must know what is Kṛṣṇa. Paraṁ brahma paraṁ dhāma pavitraṁ para... (BG 10.12). Brahma. Brahma jānātīti brāhmaṇaḥ. One who is aware of Kṛṣṇa, what is Kṛṣṇa, he is above brāhmaṇa. Brāhmaṇa qualification is already there. Because a brāhmaṇa means one who knows Kṛṣṇa, Parabrahman. That is brāhmaṇa. Brahma jānātīti brāhmaṇaḥ. Veda-pāṭhād bhaved vipro brahma jānātīti brāhmaṇaḥ. Janmanā jāyate śūdraḥ saṁskārād bhaved dvijaḥ, veda-pāṭhād bhaved vipro brahma jānātīti brāhmaṇaḥ. This is the process.
