I was having lunch with a friend and the question came up: what was the most important experience of our lives?
For me it was my first swim in the sea. Leaving uprightness, solidity, groundedness, clarity, for floating, fluidity, non-attachment, invisibility. Going from one conception of self to something so other I had to start over again in knowing who I was; and so was made aware, with a clap! of deeper recesses of interiority.
What a feeling for a small child--that inside there are more and more places to go.
