The basic principle of learning is to be there in that moment. To be nothing, unlearning etc and all big words remains only words if one is not there in the moment of learning. That moment ignites the spark within you and to hold the spark and to sustain it one needs to clean the vessel. The vessel being you; it requires huge amount of patience, practice and perserverance with lot of humbleness to hold the spark in the purest manner.
The spark is the purest essence, it is able to tear away the ignorance if one does not hold the arrogance, ignorance as more precious than the spark. The spark has to be fed with all your ignorance and all th dirt so that it can release you from the bondage, if you do not feed it, it remains hidden and then it dies out, it has to re-ignited. The spark is like a new born baby. Lot of patience, love, compassion, depth and a pure sense of sacrifice is to be there for your needs and desires, else the baby will die.
This spark is passed from one to another, one who has preserved the spark to make it a roaring fire only can give a spark to the one in need.
