There are many types of discrimination by which we can enter the portals of Truth.
Some of them are:
- Nitya-Anitya Viveka: discrimination between permanent and impermanent.
- Shareera Traya Viveka: discrimination between the three bodies, namely, the causal, subtle and the gross.
- Pancha Kosha Viveka: discrimination between the five sheaths that make up our individuality.
- Avastha Traya Viveka: discrimination between the three states of waking, dream and deep sleep.
- Kaarya Kaarana Viveka: discrimination between the cause and the effect.
- Drik Drishya Viveka: discrimination between the seer and the seen.
The purpose of all these is to discover the Self within.
