Leshyadhyana [Perception of Psychic Colours] and Svasthya [health]
The leshya and emotion permeate into each other. The leshya implies the emotion and the emotion implies the leshya. When a person becomes too violent, it should be known that too many pudgalas of the krishna (black) leshya have accumulated in him. When too many pudgalas of the krishna leshya have accumulated in a person, he would become ajitendriya. Having no control over the senses, is the result of the krishna leshya.
A person with an excessive krishna leshya in him, has that type of emotional flow. If the krishna leshya is change there would be change in the violent tendency too. The person would abhor violence. Sometimes a person may be astonished by certain events. The cruel and violent person abandons his cruel and violent tendencies in a moment. How does this happen? It happens because of the change in his leshya. If the leshya changes, his emotions also change. The colour changes under some pretext and with that, the thoughts of violence and stealing go out of his mind. One is surprised to find that a person who was a cruel murderer one moment, turned into a sadhu the next moment. The lives of Angulimala and Arjunamalakara are the evidences of this. Arjunamalakara used to kill seven persons everyday. Six men and one woman were slaughtered by him day after day. But then something happened and his violent tendency was transformed. He came to Mahavira and was initiated. It may be asked why Mahavira made such a person a monk. He was a ruthless killer who had been killing seven persons everyday for six months. How did Mahavira initiate him? Since Mahavira was able to actually see the colour, leshya emotion and abhamandal of a person, he had no difficulty in initiating him. It is believed in the field of yoga that when the acharya makes anyone his disciple, in a formal way, he gathers the information about that person's conduct, his dealings, his temperament. It is a practical test. After that test, the acharya sees his abhamandal decides whether he is qualified or not. He initiates the person whose abhamandal appears good to him. He rejects the person whose abhamandal does not appear good. The abhamandal of a person has been an important criterion for being initiated.
