Great, concise Dzogchen teaching that by recognizing our own primordial State of pure presence is the essence of the path.
Practice is the commitment to the presence of awareness, not getting distracted.
"In general not getting distracted means being present in everything we do; for example, if I think of getting up and walking, I get up with the recognition that this thought has arisen. It does not mean that I have assiduously to think, "I am getting up"; presence in what I have thought and what I am now doing is enough. You must not confuse presence with the effort of maintaining a thought."
Simply maintain a sense o presence of the recognition of the calm state without trying to define it or hope for anything, just relaxing into it without being conditioned by impulses
"The most important thing is having recognition of the movement, leaving thought free and observing it, not controlling it."
"Not hanging on to the past, not going after the future, and, without letting ourselves get involved in the illusory thoughts arising in the present moment, turning inwards and observing our own mind, leaving it in its true State beyond the limitations of past, present, and future. Without letting ourselves be conditioned by contaminating conceptualization, without passing judgment on the State itself, whether indeed it even exists, whether it will turn out to be positive or negative, etc., we must stay focused in this authentic condition and not try to correct it."
Do not fixate on trying to be calm or eliminating thoughts. "Instead, one should let the mind become relaxed, sustaining only a clear presence of its natural condition, without getting sidetracked, forgetting, or letting oneself get wrapped up in one's thoughts. When the mind is naturally released and present, it comes to itself in its authentic State. If one does not manage to continue in this state, and if various thoughts, good or bad, arise, then one should not immediately start questioning whether the mind is still in a calm state or whether the movement of thoughts has really arisen, but instead, maintaining presence and simply not drifting away, one should just try to acknowledge the thoughts. The moment the thoughts are recognized, they relax into their own condition: all the time in which we have the presence of this recognition of thoughts it is important not to get pulled off track. If the mind does get off track and the thoughts are not acknowledged, one should start attending to the presence of awareness once again....
"We must apply the essence of the practice: continuing in our own State without distraction and forgetfulness while refusing absolutely to be conditioned by the desire to modify anything. ..in all cases, the point is staying with the presence of the actual recognition of whatever one is perceiving."
