Vaiśya, they should engage themselves in agricultural production and giving protection to the cows, especially mentioned, go-rakṣya. Go-rakṣya, cow protection, is one of the items of state affairs. And now there is no cow protection. Poor cows, they deliver milk, and later on they become slaughtered. How much sinful the modern society is, and they still want peace and prosperity. That is not possible. The society must be divided—brāhmaṇa, kṣatriya, vaiśya, śūdra—and they must execute their proper duty. And the vaiśyas, they should give protection to the cows. And the śūdras, they should work under the direction of the higher three divisions. In this way there will be nice management.
Then, as it is stated during the reign of Mahārāja Yudhiṣṭhira, kāmaṁ vavarṣa parjanyaḥ (SB 1.10.4). Then nature also will help. If you keep things all right, according to the direction, then nature also will help you. Nature will give you sufficient foodstuff. Vavarṣa parjanyaḥ, kāmam. Whatever the necessities of life, it will be supplied by nature simply by proper pouring of water, vṛṣṭi. Actually, now the whole world is suffering for drought. There is scarcity of rain. And if the rain is stopped for one or two years more, there will be havoc. It is already there, havoc. In India there is famine, because they are more, mostly agriculturists. So there is famine. In other countries they have got industries. But India is not so industrially advanced. So without water, nothing can be produced.
Therefore during Mahārāja Yudhiṣṭhira's time, kāmaṁ vavarṣa parjanyaḥ (SB 1.10.4). Yajñād bhavati parjanyaḥ (BG 3.14). If you want sufficient water, then you must perform yajña. These are the indications, direction of the Vedic wisdom. So at the present moment no other yajña is possible. The only yajña, saṅkīrtana-yajña, is possible. Yajñaiḥ saṅkīrtana-prāyair yajanti hi su-medhasaḥ (SB 11.5.32). So if this Kṛṣṇa consciousness movement is taken seriously all over the world and they perform saṅkīrtana-yajña, everything will be adjusted immediately. Everything. But these rascals will not take it. They will suffer. Otherwise all directions are there. People have to take the advantage of direction, perfect direction, without any mistake, and they will be happy. So we are trying to introduce this Kṛṣṇa consciousness movement so that people may come to their senses, take advantage of it and be happy. Thank you very much. Hare Kṛṣṇa.
