Mind develops to its fullness in man, although it exists in its primitive stage in all the different aspects of creation. Man, therefore, is so called from Manas, which in Sanskrit means "mind." Many psychologists have thought that mind is the possession of man only, that the animal has no mind, but it is not so, even the plants have a mind. Where there is feeling there is mind.

There is no difference between heart and mind, although "heart" expresses more than "mind." The heart is the depth, and the surface is called mind. Plainly speaking, the depth of mind is heart, and the surface of heart is mind. Mind is a receptacle of all to which it is exposed. It is like the photographic plate; and therefore all conditions, happy or unhappy, all actions, good or bad, all that is beautiful or void of beauty, become impressed upon the mind. Its first impression is on the surface, and as the impression is retained in the mind so it reaches the depth of the heart. It is like a photographic plate; once it is developed, the impression becomes clear and deeply engraved. But the photographic plate is not creative and the heart is creative. Therefore every impression which once reaches the heart becomes as a seed in a fertile ground. The heart reproduces all it has received.

Therefore it is to the great disadvantage of the fault-finding man that he wishes to find fault with all he sees, for if he is not able to throw away immediately the undesirable impression received, which is not always so easy, he begins in due time to reproduce what he has received. Human nature is such that all the bad things man sees in another seem to him worse than they are, but when he himself does the same, he always has a reason to defend his fault. It is like partaking all that one dislikes in another only by the habit of fault-finding.

For the wise, who have risen above the ordinary faults of human life, it matters little if they find fault, but they are the ones who do not criticize. They, as a rule, overlook all that seems undesirable, and that action of overlooking itself prevents all the undesirable impressions from penetrating through their hearts. There is a natural tendency in man as in the animal to protect his heart from all hurt or harm, but that is the external heart. If man only knew what harm is brought to one's being by letting any undesirable impression enter the heart, he also would adopt the above-mentioned policy of the wise, to overlook.
