Non-dual action and meditation begins when we resolve dualistic attitudes of subject and object, of practice and person, of arising and falling away and integrating oneself not in the observation but in the experience itself. 

Many people seek meditation today for what it can do for them, for its effects and affects. While it may present a smorgasbord of benefits, seeking meditation for benefits sake is missing the point.

It takes a keen eye to discern the mirage in the desert. So too, it is not without its challenge to raise ones awareness to see through the veil of the illusory self. We all have an illusory self that we call I and me. It follows us like a shadow. We are stubbornly willing to fight for it and do everything in our will to justify it.

Mind is like the open sky, when you truly see there is only empty space. No end, no beginning; not high nor low; no length, no distance, no edge, no center. Therefore nothing truly to grasp which is why grasping for ephemeral things, objects and passing thoughts adds to the notion of unsatisfactoriness and an unskillful approach to being.

Natural mind is resting the mind. 

If mind is agitated, rest.

If resting the mind feels impossible, rest in the impossibility.

If it feels easy, rest with effortlessness.

After the mind goes searching for this why and that why, chasing thoughts and dreams, let it rest as it is.

If there is fear, relax into the fear. If there is anxiety, relax into anxiety. If there is joy, relax into joy. If there is peace, relax into peace.

If you experience doubt, difficulty or aversion in meditation then rest into the state of doubt, difficulty or aversion. There is no way around this great awareness.

Become absorbed into the vast nature of presence and then remain. Remain without aim. Remain without question. Allow concentration to settle into itself and become aware of its action as effortless.

The nature of presence is the presence of nature. We enjoy time in nature because it reminds us of our own true nature. Our essential nature. It is in harmony. Harmony is when our inner world is in accord with the external environment.

In order to know the quintessence of the Great Mystery one must relinquish all that they know. What one knows cannot truly be known, therefore the wise surrender themselves before the Great Unknown. It is the unknown that holds all that is known. The unknown is unknowable because there is no one to know it. 

This is a simplistic guideline which may help someone endeavoring into the world of modern entheogenic use to help them gain clarity and choice with deciding if the group or facilitator will meet their needs.
