Everyone is buddhist…fact!
Theists, non Theists, Agnostics, Gnostics, Satanists, Demons, Worms, are all buddhists! The word bud-dha means awake and pure, meaning recognises one’s true nature and has exhausted all karmic effects.
One’s true nature is Empty essence, Cognisant nature and unconfined Compassion.
All beings have a mind. If it moves and changes direction, it has a mind. And so, it is aware, therefore it has buddha nature…potentially enlightened! (A machine may be aware of its surroundings but will never know its own nature, or know compassion.)
You can call yourself whatever you like, but you are still this pure nature. What fun!
In over forty years I have never prayed to Shakyamuni. Only to the Bud-dha (enlightened nature), the Dharma (the teachings to recognise that enlightened nature) and the Sanga (knowledge holders of those teachings). As a buddhist-worm I practise certain methods which suit me. You may find other methods that suit you, we will still finally arrive at the same outcome – realising our true essence, knowing our true nature, and expressing compassion.
