in ecstasy it will writhe at your feet --- Kafka quote

It is not necessary that you leave the house. Remain at your table and listen. Do not even listen, only wait. Do not even wait, be wholly still and alone. The world will present itself to you for its unmasking, it can do no other, in ecstasy it will writhe at your feet.
--Kafka

Back into myself

All it takes is the tiniest little descent back into myself and things come clear again. I am in a position where I keep retreating into a turtle shell of fear and denial. It is not easy to keep my heart open. But tonight provoked by a friend teaching a meditation class I sat with a small group again and sat with myself. I arose awakened once again, if only temporarily. I know what I need to do. I think I know the cost. I do not know exactly how to do it. But I am doing it. I must. I must stay true to myself. I will surround myself with the best influences. I will be strong and nonviolent and honest and kind.
