A good description. I view active meditation different from passive meditation. Active is consciously willed, like contemplation, self-reflection, self-analysis, introspection. I do that often. Passive is just trying to remove thoughts, be in nothingness, to be calm, at peace and promote inner states of wellbeing. One is more productive than the other that just seeks to escape thoughts to promote well being but doesn't deal with the issue through self-analysis.
