In plain words
Advaita Darśanaṃ Jñānaṃ
What has the body come for? We must set such a sacred human body on the good path, in good conduct, in good thoughts, in good company. This is what Gārgī, a great renunciant, asked Yājñavalkya in the assembly of King Janaka. Yājñavalkya first married a woman named Kātyāyanī. After that he married Maitreyī. King Janaka was a karma-yogi. In his court he kept holding an assembly fit to recognise the Reality that is eternal Satya. What is transient, what is Satya? The kṣetra is Asatya; the kṣetrajña is Satya. On the question of what the way is to recognise the kṣetrajña, argument and counter-argument went on for twenty-one days. At the very last, Yājñavalkya rose. ‘I can give an answer to whoever questions me in this assembly,’ he said. ‘I am a jñānī,’ he said. At once Gārgī rose. She asked what Jñāna means. ‘Advaita darśanaṃ jñānam,’ he said. ‘Very well, I accept it. But why should you have this duality? You have two wives, Kātyāyanī and Maitreyī, have you not? Why should you not take me too as your wife?’ she asked. He could give no answer to this. ‘One is the wife, one the husband, one the mother-in-law, one the father-in-law, one the younger brother. How can one who holds these differences be a jñānī? Only the person who has recognised the feeling of the one Ātma is a true jñānī,’ she said. At this the whole assembly was struck still. ‘Sir! Yājñavalkya, you enjoy the pleasures of the senses in secret. All the enjoyments you enjoy in secret, the dogs in the bazaar enjoy too. What is the difference between this and that? Yours is in secret, theirs out in the open. That is all! Then what is the learning that belongs to humanness? Is it not said, Paṇḍitāḥ samadarśinaḥ? How can you, who lack that equal vision, answer everything in this assembly?’ she asked. When these questions were put, those in the assembly were struck with fear. Gārgī was truly a brahmacāriṇī! No one could understand her great Jñāna.
