The question has often been asked; Is Buddhism a religion or a philosophy? It does not matter what you call it. Buddhism remains what it is whatever label you may put on it. The label is immaterial. Even the label 'Buddhism' which we give to the teachings of the Buddha is of little importance. The name one gives is inessential.... In the same way Truth needs no label: it is neither Buddhist, Christian, Hindu nor Moslem. It is not the monopoly of anybody. Sectarian labels are a hindrance to the independent understanding of Truth, and they produce harmful prejudices in men's minds.

~ Walpola Rahula

There is no unmoving mover behind the movement. It is only movement. It is not correct to say that life is moving, but life is movement itself. Life and movement are not two different things. In other words, there is no thinker behind the thought. Thought itself is the thinker. If you remove the thought, there is no thinker to be found.

What we call life...is the combination of the Five Aggregates, a combination of physical and mental energies. These are constantly changing; they do not remain the same for two consecutive moments. Every moment they are born and they die. 'When the Aggregates arise, decay and die, O bhikkhu, every moment you are born, decay, and die.' This, even dow during this life time, every moment we are born and die, but we continue. If we can understand that in this life we can continue without a permanent, unchanging substance like Self or Soul, why can't we understand that those forces themselves can continue without a Self or a Soul behind them after the non-functioning of the body?

The name one gives is inessential.What's in a name? That which we call a rose, by other name would smell as sweet.
