It has no need to swing between alternatives of possibilities and probabilities. It is sure of the truth because it feels the presence of the real. Even when it is active, it knows it is active in the reality, the Self, the Supreme Being. That is Sahaja Nirvikalpa. If the mind is destroyed, as it is in sahaj samadhi, it will never slide down from their high state.
Ecstasy comes when the mind revives at the end of samadhi.
In devotion the ecstasy comes first. It is manifested by tears of joy, hair standing on end, and vocal stumbling. When the ego finally dies and the Sahaj is won, these symptoms and the ecstasies cease. That means, there is no jnana in the one who displays them. Therefore, siddhis are not worth a thought.
