Initially, to understand dharma even on an intellectual level is not at all simple. Then once we have some understanding, to put dharma into practice is even more subtle, because it requires that we go beyond our habitual patterns. Intellectually, we may recognize how our narrow-minded habits have brought about our own cycle of suffering, but at the same time we may also be afraid to engage wholeheartedly in the process of liberating these habits of ours.
This is cherishing of ego. For even if we think we want to practice the Buddhist path, to give up our ego-clinging is not easy, and we could well end up with our own ego’s version of dharma—a pseudo-dharma which will only bring more suffering instead of liberation. ~ Dzongsar Khyentse Rinpoche
