Ayahuasca is a mysterious force in all of her forms, understanding only comes thru use and Mother Aya's guidance in the dance that we call a Journey.
But before this happens a calling is tugging at you, nudging you to take the next step on your path, watch another video, read another forum, looking at another website.
Then BOOM, you know you are doing this, this new deep seated knowledge that this is your path to progression has exploded on your mind.
Much like early farmers who did not know why certain plants performed better in certain conditions, they just accepted and observed the natural flow of life and allowed it to flow thru them.
That is my advice to all seekers, accept and allow, be aware of the subtle ebbs and flows of energy surrounding you even if you dont always know why, remember " just is"
