। ॥ ६५५ ॥
In plain words
The bliss that is the original and not the reflection — that bliss is what the Self is made of: unceasing, without a second, complete, eternal, one, and untouched by fear.
Close to the Sanskrit
That bliss which stands as the original — that is defined by the bliss of the Self: perpetual, non-dual, full, eternal, one, and also fearless.
