'Thoughts' of animals are nothing but mental instincts pertaining to the sustenance of their gross body; these instincts are usually weak and short-lived and are educed as per the Nature's arrangement for their food, growth, reproduction, defense etc. But the force of human emotions, desires, thinking, mental sensitivity, convictions, faith, determination, etc is immeasurably powerful and profound. The nature and degree of this force varies among humans as per their intrinsic character and intensity of their thoughts. Most people today live an extrovert life generally revolving around sensual pleasures, instinctive joys and satisfaction of ego in one form or the other. Therefore, their thought waves are also feeble and dispersed in general. It is the strength of the inner self and the concentration of radiant thoughts that generates intense and powerful thought waves.
