If the dull-witted one leaves activities in the nature of discipline and restraint, from that moment onwards he will begin to indulge in desires and imaginations.
In describing the Knower, in contrast to the ignorant and deluded, the Sage has been emphasizing that his Self-realization makes him free and unconditioned like the Self itself. He transcends all controls, restraints and the like. At the same time, he remains active and interactive. This should not make anyone wonder whether a Knower will resort to harmful and forbidden acts. Not at all! He has nothing to gain from the world. His mind is full with contentment, arising from the Self itself. Such a hearty person cannot step into selfish tasks any time. The safeguard is inner and hence stronger. This point has also been stressed.
The dull-witted, on the other hand, cannot be the least indifferent to disciplines and restraints in his thoughts, words and deeds. The moment he relaxes on these, his mind will be a breeding ground for desires and imaginations, resulting in all kinds of indulgence, harmful to the society and himself. Human life rests upon the refinement, disciplines and restraints bring about.
If and when two persons or more live together, values and restraints become imperative. These are not optional, but compulsory. So, no relaxation or exception can be allowed. For the ignorant and deluded, they are ever indispensable. For the Knower, however, they become redundant, because he is desire-free and contentment-full. This fact rids him of all selfishness and harmfulness, the root cause of all wrong and evil.
