In plain words
So if the Buddhi can recognise for itself who it is, that is the true Buddhi. One who has come to know the whole world through cleverness alone is not a man of Buddhi. The one who has known himself is the man of Buddhi. So here we must not take this thing called Buddhi by a common name. It can be called simply the reflection of the Ātma. It can be called the reaction of the Ātma. It can be called the reflection of the Ātma. It can be called the resound of the Ātma. So the principle of the resound, the reflection and the reaction is the measure of the Buddhi.
So only when students know well the secret of Buddhi like this can each decide for himself, 'Am I a man of Buddhi, or one full of delusion?' Just because you got the First rank, just because you got an 'O' grade, you may think, 'I am very clever.' You may have cleverness. That belongs to the power of medhā. 'Mē, mē': that is the power of medhā. Medhā is a power born of that. The power of medhā is itself the power of Māyā. After Rāmacandra had spent fourteen years in the forest and returned to Ayodhyā, Kaikeyī recognised her own fault, and at a lonely moment she went to Rāma: 'My son! Through me alone have all these hardships come upon you. Though I knew you were God Himself, through my pride, through my clinging to the objects of the senses, through my attachment, I made you suffer such hardships, my son! To make amends for this, give some teaching and make my sin wear away,' she asked. Rāma did not tell her directly; He showed her the way indirectly. This has been the very secret of the Avatāra from time without beginning, this. Nothing is told directly. Only a few things may be told directly; but, but they keep speaking indirectly. The reason is that divinity is in humanness itself, so, awakening that divinity, one must try to recognise for oneself through that very divinity. If one goes on telling everything directly, he cannot understand his own divinity at all. To give him the freedom to understand his own divinity, God Himself keeps telling indirectly. 'Mother! I will give you a teaching. Go to the bank of the river Sarayū, bathe, look at whatever is around there, see what they are doing and come back,' He said.
