Your powerful spiritual samskaras, accumulated spiritual assets, have propelled you to this extremely conducive environment. Now merely wishing is enough to catapult you to Realisation. You go beyond Sabdabrahman.
Sabda or sound is the subtlest symbol of Brahman. ‘Om’ is considered to be the most powerful of all symbols. You go beyond the idol to Brahman Itself. You reach Enlightenment.
The seeker has to put in effort till the very end. Constantly, consistently, diligently. Then he gets totally cleansed of vasanas, impurities, ignorance.
This state is perfected through many janmas, births. The journey depends on how many vasanas or desires you have and the amount of effort you put in. For all you know this could be your last incarnation!
