first sate of samadhi; transcendental state where there is knowledge with awareness ...
Samprajnata Samadhi, also called savikalpa samadhi and Sabija Samadhi,[web 6][note 5] meditation with support of an object.[web 5][note 6]
Samprajata samadhi is associated with deliberation, reflection, bliss, and I-am-ness.
Object and objectless: The four stages of concentration described in the previous sutra (1.17) were all concentration with object, which is called samprajnata samadhi. In the current sutra, concentration without any object is being described, and this is called asamprajnata samadhi.
And when this stage of a single vritti alone continues, and no other thought or vritti is felt in the least, then one is said to have attained samprajnata samadhi.
