All these too are sabeej samadhi, the state where the object of focus remains, has not dissolved.

Samadhi is equivalent to yog and yog in itself is complete. Patanjali does not give types or levels of Samadhi, he gives states of Samadhi.

Samadhi literally translates as being near to Divine, not being Divine. It is not possible to achieve Divine because moksha is limited, Divinity is unlimited. What Yogsutras prescribe are ways to reach the closest to Divinity…whatever the rishis have explored, wherever they have reached, you can reach beyond that too.

Never think that you have reached the finality, even kaivalya is not finality, because there still exists something beyond…there is no finality to infinity. Don't limit yourself. There is no limit to your thought or capacity and what or where you can reach…
