In plain words
Through Ahaṅkāra and possessiveness, love grows and dwindles
True Prema does not dwindle and grow from moment to moment. Only Ahaṅkāra and possessiveness grow and dwindle! Through this Ahaṅkāra and possessiveness alone, love keeps dwindling and growing. So man must regard his Prema as the light of his life. Being human is supremely precious. Human life is worth living. A human birth is worth rejoicing in. Forgetting the value in being human, craving the pleasures and riches of Prakṛti, man forgets the divinity that is eternal and Satya. Once, Emperor Janaka went to Yājñavalkya: ‘Gurūjī! I wish to hear the story of my past birth; please tell me,’ he prayed. To this the great sage: ‘Emperor! What has passed has gone by. What use is there in recalling it? You have already seen the road you walked along. Do not brood over it. It is not for your good,’ he told him in many ways; yet, longing to hear of his past life, the king pleaded with Yājñavalkya in many ways. Yājñavalkya looked with his divine sight: ‘Janaka! The woman who is your wife in this birth was your own mother in your past birth,’ he said. With this, Emperor Janaka's mind changed completely. ‘What a wicked man I am! Today I am living with my own mother as my wife. Shame! I must give up such an evil life now,’ he thought; and from that day he regarded his wife as his mother, gave up family life, entered Vairāgya and lived in the experience of the principle of Jñāna. That is why they said, ‘Among the yogas, Rāja Yoga.’ What does Rāja Yoga mean?
Every man must carry out his duty
It is simply to pass one's time contemplating the divine while carrying out one's duties, never forgetting one's own divine feelings! Carrying out his daily dharma and fulfilling his duty, Janaka attained through Rāja Yoga the Mokṣa so hard to reach.
