In plain words
So no one has any right at all to criticise another's sādhana. Whatever anyone does, they go on receiving its result. That is what is dear to them. The result that befits that liking keeps coming to them. That is why no one at all should set out to criticise divinity in any way whatever. Divinity is divinity, and nothing else. We must receive such divinity with a feeling that is itself divine. So many sādhakas, many foreigners too, come here and do sādhana in many ways; you keep hearing of it. What I mean is this: Rāma, Kṛṣṇa, Viṣṇu, Śiva, Īśvara, Brahmā: in all these kinds of difference it appears that the forms and names differ, but recognise the truth that God is only one. This oneness, at least, you must believe. Think of Jesus, think of Rāma, think of Kṛṣṇa, think of Viṣṇu, think of Brahmā, think of Īśvara. So whatever name you give, God is only one. ‘Ekaṃsat viprā bahudhā vadanti’, many great souls have said. In all of this too, they said, ‘Om ityekākṣaraṃ brahma’. You all know that they play the harmonium here. You too know about the harmonium. But when you play the harmonium, the śruti stays one and the same. When you press each reed, sa, ri, ga, ma, pa, da, ni ring out, each a different sound. The sound differs, but the air is only one.
In just the same way, our names and forms differ, but what is called divinity is only one. So keep that divinity in your remembrance. Install that divinity in your heart. Arjuna! Do not seat Me on the outer chariot. I am no outsider. I belong to the inner house. Seat Me in the chariot that is your heart. Give Me a place there for good. There I become the very form of the mantra. As long as I am outside, I become the form of a yantra. So a yantra just does one job, but it has no life. A mantra does any work, however great. It holds back any recklessness, however great. So God is the very form of the mantra.
