If we think of the teachings as external and the practice as something added to our lives, we may study and practice for a long time without going beyond certain levels of attainment.
Milarepa discussed this problem and its solution: “External feelings create the need for interpretations and block the way to absolute realization. So forget all relative truths and look within yourself. Forget all ideas, for they will not help you.”
