In shamanic practices, to have an expansion of consciousness and divine experience practitioners drink Ayahuasca.
Ayahuasca contains a neuron inhibitor and when this neuronal network is inhibited, a high concentration of DMT is generated, so the practitioner feels and perceives experiences that are transcendental to everyday human life.
But the heart system is an even more transcendental strategic point than simply inhibiting neurons because it does stimulate the evolution of the energy system, especially the heart chakra, which is the point of connection between the most human experiences and the transcendental experiences.
Having this point developed and activated, the ordinary functioning of the brain is also inhibited. An activity similar to what happens with the Ayahuasca inhibitor and a strong sense of well-being happens in humans, a DMT-like experienced in Ayahuasca.
Since the development of the heart system and the experience with the active heart system is much longer-lasting and allows the practitioner to evolve from a more conscious state.
