The sacrificial fire kindled by the sages of Naimisaranya was certainly full of smoke and doubts because of so many flaws. The first flaw is that there is an acute scarcity of expert brahmanas able to carry out such performances successfully in this Age of Kali. Any discrepancy in such sacrifices spoils the whole show, and the result is uncertain, like agricultural enterprises. The good result of tilling the paddy field depends on providential rain, and therefore the result is uncertain. Similarly, performance of any kind of sacrifice in this Age of Kali is also uncertain. Unscrupulous greedy brahmanas of the Age of Kali induce the innocent public to such uncertain sacrificial shows without disclosing the scriptural injunction that in the Age of Kali there is no fruitful sacrificial performance but the sacrifice of the congregational chanting of the holy name of the Lord.
