A wise and learned man, even if he is clever, and has gained awareness about the exceedingly subtle Atman through the sastras, gets overpowered by tamas and does not get the doubtless Knowledge of the Atman. Gripped by delusion he considers as real and pleasurable that which is not. How powerful is the great Avrtih-sakti (the power of veiling the Truth) of the dreadful tamas!
