Kavi Santokh Singh writes in a fascinating section, where Bhai Daya Singh is answering questions from the Khalsa on the nature of the reality, this is a response defining knowledge, Vidiya ਵਿਦ੍ਯਾ ਅੰਤਸ਼ਕਰਣ ਬਿਰਤਿ ਜਬਿ ਉਪਜੀ ਅਹੰਬ੍ਰਹਮਾਸਮਿ ਦ੍ਵੈਤ ਨ ਕੋਇ ।9। Within the mind, when the state arises of 'I am Braham', then no duality remains ਬਿਰਤ ਅਖੰਡਾਕਾਰ ਅਸ 'ਵਿੱਦ੍ਯਾ' ਨਾਮ ਸੁਜਾਨ । In this state of unbroken awareness, understand that as Vidiya. ਕਾਰਣ ਕਾਰਜ ਭੇਦ ਤੇ ਦੁਬਿਧਾ ਹਾਨ ਅੱਗ੍ਯਾਨ ।10। Ignorance (agyaan) being this duality, this differentiating between causal and effect, is destroyed.
