I talk to trees (like gods/yidams I would worry if they talked back too much/outside my inner imaginings). In fact I interact/talk to most things. In other words, I listen to their message/revelation/Buddha Nature. Introspection, contemplation going inward, also means ignoring the unskilful, ignorant, dukkha, monkey mind in my opinion.
Does the Sangha include not only our human, fish and animal friends but go further still? Do we talk to sunsets with poets? Empty bowls full of potential giving?
How is the relationship to the outer, part of the inner journey?
