The obsessive need to understand enlightenment or anything for that matter, is the very thing that’s stopping you from experiencing this present moment in its fullness. When resting in the present moment it’s seen that there’s nothing missing and no needs are unmet; there’s no understanding that you need that could add or take away from what you essentially are.
You are that which sees everything, you are what is being sought. There’s no understanding that would bring about this realization. Understanding is only ever something that the mind ‘gets’. That’s not to say that some understanding might come; but you as consciousness are prior to any understanding. The understanding arises within you, not the other way around. You exist before any understanding.
