Nirodha parinama (Yoga)

This is the holding of the state, normally instantaneous, between two impressions in consciousness so that there is no impression at all and the mind is unmodified. It is called the [Niruddha]

state. Once this state is achieved on one plane the consciousness passes to the next plane and the process of three transformations is repeated.

The third of three mental transformations described by Patanjali.
