I have learnt that sharing knowledge like sharing your japam (yoga term for meditation subject), leads to less personal power.
Curiously; writing knowledge down does not have the same result.
I believe this is because reading is like a contract between the author and the reader. This contract allows the sharing of knowledge without the loss of power, in fact you can empower the reader with out losing any yourself.
So I am sharing with you to aid your power reserves and I do it not for selfish reasons, Instead the reason I choose to believe in this is that knowledge needs to be shared.
Its almost as if its the knowledge trying to get out and I am just giving it a helping hand. I am just an interpreter, a conduit , I am trying to understand ancient texts and translate them into a language that Ii understand and hopefully you do to.
