I listened to a yogi talking about mindfulness. He mentioned a session he had with a woman where they where working on the concept of flow. The woman had an experience of flow when she was bitten by a shark.
She said that if she could make a drink that would create that feeling she would addicted the world.
I think about that sometimes.
That's reminiscent of Livingstone's description of the time he was mauled by a lion:
"The shock produced a stupor similar to that which seems to be felt by a mouse after the first shake of the cat. It caused a sort of dreaminess, in which there was no sense of pain nor feeling of terror, though quite conscious of all that was happening."
