Buddha renounced every worldly happiness because he wanted to share with the whole world his happiness which was to be had by men who sacrificed and suffered in the search for truth.
For the great majority of mankind are satisfied with appearances, as though they were realities, and are often more influenced by the things that seem than by those that are.
As for the search for truth, I know from my own painful searching, with its many blind alleys, how hard it is to take a reliable step, be it ever so small, towards the understanding of that which is truly significant.
Even great spirits have only their five-fingers' breadth of experience - just beyond it their thinking ceases and their endless empty space and stupidity begins.
My great religion is a belief in the blood, the flesh, as being wiser than the intellect. We can go wrong in our minds. But what our blood feels and believes and says, is always true. The intellect is only a bit and a bridle.
By this time, like one who had set out on his way by night, and travelled through a region of smooth or idle dreams, our history now arrives on the confines, where daylight and truth meet us with a clear dawn, representing to our view, though at a far distance, true colours and shapes.
