This is the familiar resistance that many man experiences, often when a second round of drinking Ayahuasca is announced. Especially if it is your first connection to Ayahuasca.
Realize that a lot of shame, guilt, lack of self-confidence and victimization resides within us. Especially when there have been impactful / traumatic experiences which we have tucked away deeply (pain body). It requires coming out of the role of victimhood, only then change can occur.
This requires curiosity about yourself. You have a right to know what happened to you or why you created blockages. Regardless of the intensity of an event. If it is blocking you, then this is a problem that needs your attention. Go beyond the resistance.
Note; If you are fully connected to Ayahuasca and she is strong enough, the facilitator should notice this and respect your choice not to drink the second time.
However, 9 out of 10 it’s the resistance of not wanting to know, where the mind takes over; controlling.
