That day, Varuna came to the forest in search of his son. He was happy to see his son in samadhi. From the effulgence which shone on Brighu's face, he knew that his son had realised that 'Bliss is Brahman'. In the upanishadic age, parents and preceptors used to encourage their pupils to ask questions, yet they would not give them immediate answers. They would advise them to carry on self enquiry and find out the answers for themselves.
Experience is the best teacher.
