Sound of Silence, tranquility and equanimity, not-self, for goodness sake, samadhi sensations, letting go in meditation, realizing Nibbana and sticking around afterwards.
A reflection on the teaching of Ajahn Ganha:
"We have to do good for the sake of goodness. We observe the precepts for the sake of keeping precepts. When we practice samadhi meditation, we practice for the sake of meditation. When we cultivate our wisdom, it is just for the sake of cultivating the wisdom. Then we can gain the peacefulness of mind and wisdom at the same time."
