Then the minds one-pointedness concentration changes again, when its now calm impressions merge into a continuous state.
Here Patanjali conveys a new transformation in the mind, on two levels:
Firstly, a situation where only a minor disturbance remains, but having moments of calmness, like separate waves crashing on the shore.
Secondly, the ultimate level, whereby this state of one-pointed focus becomes a constant experience, a continuous still ocean. This unique state of being makes each moment identical to the previous one. There is no separation between moments and any sense of time is removed.
