Let us solve four problems by the process of 'seeing'. Solving the problems of sleeplessness and disturbed digestive system is at the physical level. The third problem concerns the good mental condition. Let us develop greater awareness of the mind, not indulge in undesirable thinking, because when a person thinks bad things about another person, that person may or may not be affected, but the person who indulges in such thinking is definitely affected.
Our commentators have described this in beautiful words by mentioning how undesirable pudgalas are radiated on account of undesirable thinking. How do these pudgalas affect our body? Let us learn to perceive the mind as well - The mind too is a centre. Let us observe whatever thoughts in the mind. Let us see our thinking. Our thinking would h come healthy if we observe our thoughts. It would also suit in good mental and physical health.
