You have seen that cakra of our Gauḍīya Mission? You remember, Rāmadāsa? So one side is called . . . Caitanya Mahāprabhu is in the middle, and one side is bhāgavata side, another side is pāñcarātriki side. So pāñcarātriki side is Lakṣmī-Nārāyaṇa sitting on the throne, and bhāgavata side is Rādhā-Kṛṣṇa.
So bhāgavata side is very difficult. Unless one is purified from the pāñcarātriki side, it is very difficult to go to the bhāgavata side. But Caitanya Mahāprabhu has given this simple process: chanting Hare Kṛṣṇa, kīrtana, and hearing the Śrīmad-Bhāgavatam. And pursuant to these two principles one can install Rādhā-Kṛṣṇa Deity and serving.
Five things: vaiṣṇava-sevā, to serve the Vaiṣṇava pure devotee; and to hear; chanting; and to worship the Deity; and to hear Śrīmad-Bhāgavatam, chanting. Chanting is kīrtana, and hearing Śrīmad-Bhāgavatam. Hearing and chanting and serving and worshiping, and if possible to live in a sacred place like Vṛndāvana and Mathurā. These five things are recommended by Lord Caitanya for quick advancement of spiritual life, very quick.
So the vipra stage . . . we are talking of how to come to the vipra stage. The first stage, everyone is on the śūdra platform. Then by purificatory process, by understanding of this Vedic knowledge, janmanā jāyate śūdraḥ saṁskārād bhaved dvijaḥ, that by initiation he is twice-born . . . first born father and mother, and next birth is the father is the spiritual master and mother is the scripture. That means the . . . as the . . . materially the father agitates the mother and the body is formed, similarly, spiritually, the spiritual master agitates the mother of Vedic knowledge, and the spiritual body is formed. This is called dvijaḥ.
And the sacred thread means that one, he . . . one who has attained the second birth, saṁskārād bhava dvija. And after becoming dvijaḥ, initiation, it does not mean that you are perfect. Perfection is not . . . that means you are accepted. Now you have to make yourself advanced by understanding Vedic . . . veda-pāṭhād bhaved vipraḥ, vedaiś ca sarvair.
Veda-pāṭhād means to understand Kṛṣṇa. Vedaiś ca sarvair aham eva vedyo (BG 15.15).
