"If thought is only a part of the whole, can it ever contain the whole?" -- Physicist David Bohm

Physicist Werner Heisenberg in Science and Philosophy:
"Any concepts or words which have been formed in the past through the interplay between the world and ourselves are not really sharply defined with respect to their meaning: that is to say, we do not know exactly how far they will help us in finding our way in the world. We often know that they can be applied to a wide range of inner or outer experience, but we practically never know precisely the limits of their applicability. This is true even of the simplest and most general concepts like 'existence' and 'space and time'. Therefore, it will never be possible by pure reason to arrive at some absolute truth."

The second stanza of Patanjali's Yoga Sutra reads: "Yogas Chitta Vritti Nirodha"; that is, "The technical aim of Yoga is the intentional stopping of the spontaneous fluctuations of mind/thought." Why? To address the problem so well described by Prof. Heisenberg above.

Excerpt from The Acintita Sutta (below)
The Middle Length Discourses of The Buddha

"The following questions cannot be thought about to a completion:

1.  What is the origin of self and world?
   
2.  What is the precise formulation of the law of Karma?
   
3.  During the state of meditative absorption, what abilities/powers arise in the meditator?
   
4.  What is the extent of the knowledge and power of a Buddha?
