“Do we ever understand what we think? We only understand that thinking which is a mere equation, and from which nothing comes out but what we have put in. That is the working of the intellect. But beyond that there is a thinking in primordial images—in symbols which are older than historical man; which have been ingrained in him from earliest times, and, eternally living, outlasting generations, still make up the groundwork of the human psyche. It is only possible to live the fullest life when we are in harmony with theses symbols; wisdom is a return to them. It is neither a question of belief nor of knowledge, but of the agreement of our thinking with the primordial images of the unconscious. They are the source of all our conscious thoughts, and one of these primordial thoughts is the idea of life after death.” ~Jung
Meditate before you venture, take it seriously, use it as medicinal—it is good psychotherapy if needed. Realize that you, the Earth, others, and the Universe are all one and the same process. Then take that knowledge back to become, as you already are, one with nature. Eternity in every moment. Divinity in every particle. All is one organism.
