The first preparative step to meditation begins with the practice of one-pointedness. Our senses are attracted to external subjects. We need to redirect them inwards. This process the Jain agamas (Scriptures) call Pratisanlinta ; its practice helps in increasing concentration and reducing instability.
Indian philosophy, or ‘darsha’, is based on perception, or seeing. In fact, 'darsha’ means seeing or perceiving. Its meaning has changed now. The philosophy being taught in colleges and universities today is based on inference and reasoning, but in ancient times it stood for direct apprehension. Not inference, not abstract reasoning, not causation, not universality or pervasiveness, but sheer apprehension. Today, we have lost the power to see and we fail to distinguish between thinking and perceiving.
