Text 16

tatraivam sati kartaram
atmanam kevalam tu yah
pasyaty akrita-buddhitvan
na sa pasyati durmatih

Translation

Therefore one who thinks himself the only doer, not considering the five factors, is certainly not very intelligent and cannot see things as they are.

Commentary by Srila Prabhupada

A foolish person cannot understand that the Supersoul is sitting as a friend within and conducting his actions. Although the material causes are the place, the worker, the endeavor and the senses, the final cause is the Supreme, the Personality of Godhead. Therefore, one should see not only the four material causes but the supreme efficient cause as well. One who does not see the Supreme thinks himself to be the doer.

Commentary by Sri Visvanatha Cakravarti Thakur

Then what happens? Though these five are causes of action (tatra evam), one who sees only the self, the jiva, as the doer, without association of anything else, does not see, being a fool (durmatih), because of impure intelligence (akrta buddhitvat). One may say that such a foolish person is blind.
