Saintly people like Jada Bharata do not speak ordinary words. Whatever they say is approved by great yogis and those advanced in spiritual life. That is the difference between ordinary people and saintly people. The listener must also be advanced to understand the words of such exalted, spiritually advanced people as Jada Bharata. Bhagavad-gita was spoken to Arjuna, not to others. Lord Krsna especially selected Arjuna for instruction in spiritual knowledge because Arjuna happened to be a great devotee and confidential friend. Similarly, great personalities also speak to the advanced, not to sudras, vaisyas, women or unintelligent men. Sometimes it is very risky to give great philosophical instructions to ordinary people, but Sri Caitanya Mahaprabhu, for the benefit of the fallen souls of Kali-yuga, has given us a very nice instrument, the chanting of the Hare Krsna mantra. The general mass of people, although sudras and less, can be purified by chanting this Hare Krsna mantra. Then they can understand the exalted philosophical statements of Bhagavad-gita and Srimad-Bhagavatam. Our Krsna consciousness movement has therefore adopted the chanting of the Hare Krsna maha-mantra for the general masses. When people gradually become purified, they are instructed in the lessons of Bhagavad-gita and Srimad-Bhagavatam. Materialistic people like stri, sudra and dvija-bandhu cannot understand words of spiritual advancement, yet one can take to the shelter of a Vaisnava, for he knows the art of enlightening even sudras in the highly elevated subject matter spoken in Bhagavad-gita and Srimad-Bhagavatam.
