Atman
Atman is that which is left after all the personal limiting adjuncts have been negated, by the process of: 'I' is not this body, 'I' is not this vital sheath, 'I' is not this mind, 'I' is not this intellect and 'I' is not this causal ignorance.
Knowledge and Action
Knowledge and action are two sides of the same coin.
To be established well in one, is to practise both.
Sacrifices
One sacrifices to the other - the seed sacrificing itself gives rise to the tree, the tree sacrifices itself to produce the fruit - food.
Vanity
One man's vanity shields another's transgression with a seemingly lofty rationalisation.
Mind Control
The power of delusion, of ignorance, of animal desires and instincts, is so strong that any attempt at controlling the mind is seriously resented by it.
