What I find interesting in this testimony from Krishna Das is that his teacher found a way to demonstrate that meditation does not center in one's personal suffering or discomfort. But rather that meditation encompasses the whole process of suffering in its impersonal dimension, is inclusive of all the suffering both inflicted and suffered by sentient beings since the beginning of time. Raja Yoga would have one inquire into the causes of suffering and one's participation and responsibility to bring one to realize the personal/impersonal dimension of suffering. While I understand this teacher to have a more devotional yet no less effective approach.
I have been touched by someone who did sustain an unchanging love for all beings but whose teachings might appear more abstract at first view. His concern for the world and its fate was immense.
