In plain words
'God Himself scorched it and went': that is, He was revealing well, in every matter, the truth that He Himself is God. Our student said that He showed Yaśodā all the worlds inside His mouth. When Balarāma said He had eaten mud and come…, she told Him to open His mouth. Mother! To eat mud, am I a baby? Am I hungry? Am I mad? Mother, they say I have eaten mud. Am I a little child? Am I a hungry boy? No. Am I mad? No. Why would I eat mud? 'Whether there is mud in My mouth or not, look and see it yourself,' He said. When she looked, all the worlds were showing. Yaśodā could not believe it. She herself had every kind of doubt. Is this some dream of mine? Is it the Māyā of Viṣṇu? Am I not Yaśodā Devī? A doubt about herself came to her own self. Secrets of greatness is faith in yourself and faith in God. First of all there must be trust in yourselves. Having trust in yourself is itself trust in God. Those who cannot believe in themselves cannot believe in God. So, because she had no trust in herself, Yaśodā could not believe in Kṛṣṇa. What is the reason for this? Worldly affection alone is the reason for this. She kept nourishing this bodily bond, the bond of 'I am the mother and He is the son.'
The story of Kṛṣṇa is most wondrous. That is why Vyāsa said:
Wondrous, and sacred for the three worlds, cutters of the creeper of worldly existence, true friends, the springtime of the forest of sages, are the stories of the Lord Viṣṇu.
How wondrous this story of the Lord Viṣṇu is! All of it is wondrous. His games, His songs, everything is wondrous. The Avatāras themselves are wonders. Not being able to know it is a greater wonder. Not being able to experience it is a still greater wonder. To suffer sorrow while living in the very presence is a greater wonder. Standing in knee-deep water, crying, 'Thirst, thirst,' someone gave up his life, it seems. In just the same way, to live right near the Avatāras, move about with the Avatāras, go about with the Avatāras, playing and singing, and not be able to understand the tattva of the Avatāra: that is itself a wonder. When we understand it, Ānanda is had by us. Humanness is a most sacred life. When one truly lives in faith in God, the whole of life becomes a march of victory.
