So nana-śāstra-vicaraṇaika-nipunau. So we have to study the Vedic literature very carefully, following the footsteps of Gosvāmīs. Not only chanting. This is also required, kṛṣṇot-kīrtana-gāna. But this is meant . . . if you simply go on chanting without reading books, that is also good, especially in this age, because nobody has got power to study books. Education is very less. So still, one who is able, they should consider all this. We have given in English translation so many important books. You study, and chant this Hare Kṛṣṇa mantra like this, and that is the following the footsteps of Gosvāmīs. Ācāryopāsanā. We have to worship the ācāryas. That is recommended in the Bhagavad-gītā for making progress in spiritual life, ācāryopāsanā.
So this is ācāryopāsanā, by reading their books, nana-śāstra-vicaraṇaika-nipunau sad-dharma-samsthapakau. Why studying so many books? For the sake of establishing real religious life, sad-dharma. There are two kinds of dharmas, religious, religions: pravṛtti-mārga, nivṛtti-mārga. Pravṛtti-mārga means materialism, and nivṛtti-mārga means spiritualism. Pravṛtti means because we had intention to enjoy this material world, therefore we have been given this material body by the energy of Kṛṣṇa, prakṛteḥ kriyamāṇāni (BG 3.27), by the . . . for associating with this material world.
We are spirit soul. We have been given this chance to associate with the material world, this material, which is called . . . so there is still the rules and regulation. You associate, you enjoy this material world under this instruction, then you'll not be fallen, you'll not be implicated. That śāstra. Śāstra gives you codes. Just like when I immigrated in this land, they gave me one paper, "Welcome," and some immigration rules. That is śāstra. Similarly, the Vedas means the rules and regulation which, following, they'll very happily live in this material world.
