Samadhi -> a superconscious state 
The first chapter of Pantajalis Yoga Sutras is samadhipada. Translated, means "Foundations of Union/Conclusion/Completion."
Swami Brahamananda suggests there are three levels of Samadhi
- Savikalpa Samadhi - superconscious vision with thought
- Nirvikalpa Samadi superconscious vision without thought.
- Finally "the realization of that which is beyond thought and speech. In this state there is nothing to be seen; nothing to be heard. Everything is lost in the Infinite."
