In the world of form, everything changes and evolves. So, there was a certain evolution of the teaching. Different pointers came in, different stories, different approaches to the truth, which always is the same.
Eckhart TolleUnderneath the world of sense perceptions and the world of mind activity, there is the vastness of being. There's a vast spaciousness. There's a vast stillness and there's a little ripple activity on the surface, which isn't separate, just like the ripples are not separate from the ocean.
Eckhart Tolle
