First class person - they learn from hearing only.
Second class person - they hear but still they do not learn. So they only learn through experience.
Third class person – they hear and then they experience the trouble - and still they don’t learn – those are fools.
But as a devotee, most of us are second class. Most of us learn through experience.
(Kadamba Kanana Swami, Canberra, October 2010)
