Rely On Your Own Experience
What I tell you is my own. It can never be yours. What you need is your own, something which comes out of your own inner being. If it is not that, what is the use of listening to others and remembering all those words. Words cannot serve you when you need them.
For instance, when you are at the moment of death, some critical moment, you cannot just open up your books and see what passage is most needed to meet this crisis, or the moment of impending death. You have to meet the situation in your own way; and your own way comes out of yourself, never from others' minds or teachings.
