How to Do an Effective Inquiry Into Life

When your mind gets filled with a lot of ideas, then it's like a cup that is full. And when a cup is full, you can't add more to it. Actual reality comes to you only in one form, through direct experience and through no other form. Your speculations and ideas about it are always suspect and could always be overruled by direct experience. This is critical, because to do an effective inquiry, you have to ask yourself, how do i do inquiry accurately? Which takes you into the domain of epistemology.
