Once the Sanzer, the [author of the] Divrei Hayim stood up and positioned himself to study in the evening – he stood at a lectern, one foot on the ground and the other – the sick foot on the lectern.
He stood like that until morning and did not move.
When they arrived for prayer in the morning he awoke up from his studies and said: “What? What? I thought not even an hour had passed since I stood to study.”
