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).
Because Vedic knowledge means to understand Kṛṣṇa. The more you understand Kṛṣṇa, then you will become vipra. And when you become vipra, then there are twelve qualifications. That is being stated here—viprād dvi-ṣaḍ-guṇa-yutād aravinda-nābha (SB 7.9.10).
Twelve items, just like controlling the senses, subduing the mind, subduing the tongue—sāma, dama, titikṣā—to be tolerant, then simplicity, then full faith in the scriptures, knowledge, understanding Kṛṣṇa. In this way there are twelve qualification.
