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.
