There is no "how to drop it”, because that is only another form of continuity. To drop opinion, belief, attachment, greed, or envy is to die - to die every day, every moment. If there is the coming to an end of all ambition from moment to moment, then you will know the extraordinary state of being nothing, of coming to the abyss of an eternal movement, as it were, and dropping over the edge - which is death.
