While it is certainly useful to study the dharma from qualified dharma teachers and from sutta discussions, one has to know the teachings relatively well to have a certain level of understandng. But all these knowledge can just be superficial learning at best. This is what we normally call as textbook learning. To really benefit from the learning the dharma, we will have to internalize the teachings. This means making the dharma a key part of our lives. For instance by adhering closely to the precepts and/or leading your life according to the eightfold noble path. A better way to assimilate the teachings is to realise it at higher level so that it becomes a natural part of us. The key thing is to investigate the dharma through our meditation practice. If our mind is quiet enough and our body fully relaxed, chances are that we might be able to feel the soft and gentle energy flow sensation, the silence, inner peace and the bliss for us to investigate the dharma. And coupled with mindfulness, your faith and energy will help to propel you to be trully on the path towards enlightenment.
