We could say that all teachings are basically a way of subjugating or shredding our ego. And depending on how much the lesson of the subjugation of the ego is taking hold in us, that much reality is being presented to us. All dharmas that have been taught are connected with that. There is no other dharma, particularly in the teachings of Buddha.
...
That is why this slogan goes along with another saying of the Kadampa teachers, which is "The shedding of the ego is the scale that measures the practitioner." If you have more ego, you will be heavier on that scale: if you have less ego, you will be lighter. That is the measure of how much meditation and awareness have developed, and how much mindlessness has been overcome.
