Enquiry, analysis. (Glossary for the Vahinis)
Vicharana is the process of discriminating between the right and wrong, good and evil, the transient and the eternal. In ordinary life, you have to separate the rice from stones, the grain from chaff. Everyone needs to cultivate discrimination by the process of enquiry. Even a monkey knows that it has to remove the rind to eat the fruit inside. Likewise man has to distinguish between the Atma and the Anatma the Spirit and matter, the Real and the unreal, the good and evil, right and wrong and follow the right path. Buddhi grahyam atindriyam. The intelligence grasps what is beyond senses. We have to transcend the senses so that we may seek the Real and the Eternal and reject the ephemeral and perishable. The things of the world are subject to birth, growth, decay and death. (SS June 87, p. 154)
