श्लोक कहता है

Whoever finds his happiness within, his rest within, his light within — that practitioner, having become the infinite, reaches the peace of the infinite.

सरल शब्दों में

Three things, all relocated to the same place.

Happiness. Rest. Light.

And then a phrase that the rest of the chapter has been building toward: having become it, he reaches it.

आपने इसे कहाँ महसूस किया है

The wheel room has no window and no clock in it. Four hours go by. The potter comes out and cannot tell you whether it was a good session, because the question did not come up while he was in there.

और गहराई में

Brahma-bhūtaḥ — having become the infinite. The order of the sentence is the point: becoming comes first, arriving comes second.

That rules out one very common picture, in which you remain what you are and travel toward something else. Nothing is being travelled to here. The reaching is what follows a change in what you are.

Antar-ārāma — whose pleasure-garden is within. It is a domestic word rather than a lofty one. An ārāma is a garden, a resting place, somewhere you go to be at ease.

So the image is not of a fortress or an escape. It is of somewhere pleasant that happens to be indoors, and which does not close.

For a reader the test is ordinary and slightly uncomfortable. When you have an unplanned free hour and nobody to see it, where do you go, and does it require anything to be delivered?
