What about the gnostic teachings,i assist to a gnostic school IGA Institute gnostic of anthropology which is very interesting and helpful to stay calm ,relaxed,which the founder is Vm Samael Aun Weor,they talk really good aspect of the mind,how not be angry,etc.
However in the aspect of talking about astral it is usually talked that you can go to the Gnostic church in astral,meet with the great white brotherhood,there,and i dont want to be searching my whole life an illusion ,if it is,or if it is not ,but i have experienced some phase experiences as Michael said going into water and meeting a whale,which was awesome,so my question would be it is worhty trying to look for that there or enjoying going under water,going to a sauna,etc
Thanks!
