From Dakini Teachings, [B]Shravaka’s State of Cessation[/B], is defined as:
In the context of Mahayana or Vajrayana practice, this state is used in a derogatory sense and is renowned as a severe sidetrack from the path of the enlightenment of the buddhas. The mistake comes from regarding meditation practice as being the act of cultivating and fixating on a state in which sensations and thoughts are absent.
When understood correctly, Patanjali’s yoga will be found to agree with this point of view.
Here and Now refers to space and time. If our mental processes involve memories, our mind is occupied with the past and places that are different from where we are in the present. Similarly our minds can be occupied with the future through worrying or planning or imagining. This is a unique ability of the mind, as the senses and the organs of action operate only in the present time. When we are focused on the present, our minds and emotions are fully engaged with our bodies and senses, and with others who happen to experience this moment with us.
Obviously we cannot live each and every moment in the Here and Now. In fact, some of us may actually spend little time focused on the present, because we are so caught up our memories or imaginations, with worrying and planning for the future. Here and Now can be a place of refuge, when we need a break from our daily troubles and worries. Also, Here and Now means being mindful. As we go about our daily activities, we need to be focused and not distracted by things that happened or may happen in other places and times.
As for the self as witness and not as doer, this is a difficult concept and one which need not concern us unduly. It means that the phenomenal self, the “I” or ego that is the agent of all our actions is not the ultimate self that is sought by seekers of enlightenment or liberation. We obviously cannot go about our daily lives as witness and not as doer, but to experience our self as witness is an object (or subject) of yoga.
