Nirvikalpa Samadhi is sometimes spelled Nirbikalpa Samadhi
Nirvikalpa Samadhi is achieved through the advanced and prolonged practice of Kriya Yoga and is the state of oneness with atman - the self or soul.
through the complete practice of Kriya Yoga and relevant teachings - all attachments to material world and all karma is dissolved. then in an advanced session of Kriya Yoga all awareness is withdrawn step by step from physical body, astral body, causal body until self realization or oneness with soul is achieved.
During the progress of above steps - breathing ceases, heart activity stops completely. Aware and fully conscious oneness with soul is then achieved in a most loving way and all cells of physical body are flooded with an ocean of divine love and divine bliss for any period of duration - hours, days, weeks until kriya yogi is shifting his awareness from soul back to physical body.
Nirvikalpa Samadhi is the preparatory step of Maha Samadhi and serves as extreme uplifting of all body vibration and leads to complete healing of karmic wounds to open doors to God and divine love for further progress on your way to God.
Once you reach Nirbikalpa Samadhi, you need to go directly into next level of Samadhi to achieve oneness with God = Maha Samadhi. God is Love - used as Mantram is the key to that final step!
