There are any number of self-proclaimed atheists in Buddhism many of whom are Westerners. The idea of atheism should be the non-belief in a demiurge, that is, a creator god. Our universe may not require a creator. At the highest level it might well be self-generating. Personally, I don’t mind atheists becoming Buddhists. But this is not what is happening in Buddhism today. I often find that those who profess to be atheists practice, in addition, irreligion.
If we accept that religion involves connecting with unconditioned, infinite spirit which is not limited and constrained in the way humans are, then irreligion carries with it a destructive intent to limit what man can know, spiritually; to keep mankind within the boundaries of the finite. This inevitably leads us to a false and dangerous path. It is one of nihilism which carries with it the general sense of meaninglessness and certainly the belief that all knowledge is relative. In other words, everyone is right which can easily mean that everyone is wrong.
Those with whom I have communicated which I would regard as irreligionists, have an unconscious drive to irreligionize Buddhism. They seem uncomfortable and irritated by the notion of a higher world that we can access by way of meditation; which is the very stuff from which our finite world is composed. It is not surprising that they latch onto Nagarjuna by turning him into a second Buddha not even understanding the message of the first Buddha! If I had to encapsulate an irreligionized Buddhism (Nagarjunarism) it would be found in these words:
The teaching of emptiness shows that all phenomena are free from inherent existence. They have no real basis; nor are they definable in terms of themselves except that they are dependently related to each other. Using the same line of reasoning, as we look within ourselves there is no true nature, âtman, or unchanging identity or ground. There is nothing there!
What this leaves us with, if we permit ourselves to think about it, life is a continuous struggle with no escape except death (hoping that death is final). As Nietzsche writes in his book, Will to Power, “Every belief, every considering-something-true, is necessarily false because there simply is no true world." Certainly from Hume to Nietzsche religion has been under siege and the siege continues which has become irreligion. By throwing out the bathwater of religion, irreligion is also throwing out the baby Buddha.
