other religions

Regarding religion, not only at present, but also in the past, all of them are described as pseudo-religions. The Bhagavat (Purana) has condemned such pseudo-religion in the second verse of the first chapter, first canto. Under the spell of material energy, man is forgetful of his eternal relationship with God. They create some religion to derive some material benefit as they create political organization for mutual undisturbed sense gratification. So religion is also a part of that concept of life. As such, in most of the religions you will find some instruction on morality and goodness, and God consciousness is superfluous. So except Krsna Consciousness or Bhagavata Dharma or religion of the Bhagavata, any other system of religion is only pretension, that is the fact. It is not therefore surprising that your impression of the meeting of the Jews and Christians, where you had opportunity to speak, was that they were lacking so much in God-consciousness. So far we are concerned, our principle is to live with God as actual fact, and not to make God a supplying agent.
