From the early great Upanishads, the recognition ATHMAN = BRAHMAN (the personal self equals the omnipresent, all-comprehending eternal self) was in I… - Erwin Schrödinger

However insignificant the frictional and heating effects in a clock may be from the practical point of view, there can be no doubt that the second attitude, which does not neglect them, is the more fundamental one, even when we are faced with the regular motion of a clock that is driven by a spring. For it must not be believed that the driving mechanism really does away with the statistical nature of the process. The true physical picture includes the possibility that even a regularly going clock should all at once invert its motion and, working backward, rewind its own spring – at the expense of the heat of the environment.

The multiplicity is only apparent. This is the doctrine of the Upanishads. And not of the Upanishads only. The mystical experience of the union with God regularly leads to this view, unless strong prejudices stand in the way.

The spread, both in width and depth, of the
multifarious branches of knowledge during
the last hundred odd years has confronted us
with a queer dilemma. We feel clearly that we
are only now beginning to acquire reliable
material for welding together the sum total of all
that is known into a whole; but, on the other
hand, it has become next to impossible for a
single mind fully to command more than a small
specialized portion of it. I can see no other
escape from this dilemma ... than that some of us should venture to embark on a synthesis of facts and theories, albeit with second-hand and incomplete knowledge of some of them -and at the risk of making fools of ourselves.
