Q: What are the indicators based on which I shall be enabled to find out for myself whether I am doing vichara correctly or not? 
B: If vichara has resulted in a state of mind wherein it abides as identical with pure Subjective Consciousness, then you have done it correctly. However, it is not easy for the neophyte to tell whether his mind is presently abiding as identical with pure Subjective Consciousness, because the torpid mental state of manolayam [state where mind structures are hazily projected] is often mistakenly regarded as being the tabula-rasa mental state of pure Subjective Consciousness. 
      When mind abides as identical with pure Subjective Consciousness, it unmistakeably scintillates ‘I’-’I’. Thus, the definitive answer to your question is that vichara has been done correctly when doing it has resulted in the Aham Sphurana flashing forth.
 

Q: And how to recognise the Aham Sphurana when it ‘flashes forth’? 
B: There is no possibility of mistaking it when the experience actually occurs. Whatever description is given, is not only useless but also counter-productive, because if a description of the experience of Aham Sphurana is given, the mind twists and contorts the present banal experience of outward protruding, satiation craving mental impulses into one that seems to perfectly match with the description given; because it wants to avoid getting destroyed.
       So, even if you have heard a description of the experience of the Aham Sphurana being furnished in this Hall, please make no effort to recollect it. When the Aham Sphurana actually flashes forth, you will know it alright. Cognition of the Aham Sphurana is not based on intellectual corroboration it is a direct experience of the Self, inferior only to the Sahajastithi of the Jnani.
