In plain words
Ādi Śaṅkara's Ideal
One in mind, one in speech, one in action are the great-souled.
This oneness of thought, word and bodily deed is itself the true principle of the Ātma. “Manassanyat vacassanyat karmaṇyanyat durātmanām”: what is the reason for becoming a wicked man? In the mind the resolve is one thing. In the word, another. In the deeds, yet another. The proper study of mankind is man. Mind, word and deed: these three have not become one. This is a great sin. To teach the world this, Ādi Śaṅkara went on making pilgrimages of this kind. In all that Śaṅkara did, every single step was, each one, a teaching in itself. He is coming back from that holy place of Kāśī. Someone sitting under a tree is reciting from Pāṇini's book, “Ḍukṛñkaraṇe, ḍukṛñkaraṇe.” He saw him: he must give him a teaching. ‘My dear! What is it you are reciting?’ ‘I am reciting Pāṇini's grammar,’ he said. ‘What is the fruit that comes of this?’ he asked. ‘As long as I am here, I shall live happily along with my family,’ he said. ‘How long will you live!’ ‘As long as I live in this body.’ ‘After that?’ ‘I don't know,’ he said. Then he said, ‘You madman! The physical body, physical wealth, the physical world, physical books: all these are physical. As long as these last, you will be happy. First of all, earn for yourself the Ānanda that is eternal, that is true, that is everlasting, the Ānanda you will enjoy after you die,’ he said.
Worship Govinda, worship Govinda, worship Govinda, O deluded mind! When the appointed time has come near, ḍukṛñkaraṇe will not, will not save you.
This ḍukṛñkaraṇe will not, will not save you. Scholarship will never save you. Will this grammar, these studies, save you? All these kinds of learning are rooting out the divinity that is in humanness.
