A theory is like medicine (or government): often useless, sometimes necessary, always self-serving, and on occasion lethal. So it needs to be used with care, moderation, and close adult supervision.

...a man must go forth from where he stands
he cannot jump to the absolute, he must evolve toward it (can you hear that)
Krishna says at any given moment in time we are what we are
Arjuna we have to accept the consequences of being ourselves
and only through this acceptance can we begin to evolve further
we may select the battleground but we cannot avoid the battle...
