1. What is Viveka?
When you are fully aware of the magnitude of human sufferings in this miserable, relative world, you will naturally begin to discriminate between what is real and what is unreal.
Brahman is real and Jagat is unreal.
This is Viveka.
Then sincerity or Sraddha will develop.
Then aspiration or keen longing to realise God will be felt.
Then you will have to remember the Truth constantly.
Then you will have to assert constantly: "Aham Brahmasmi-I am Brahman."
By incessant practice, Nama, Rupa and Sankalpa will vanish and you will realise Brahman.
This is Vedantic Sadhana. Discrimination, sincerity, aspiration, remembering Truth always, assertion and then Realisation are the various stages or means for realisation of Brahman.
