However much I revere and respect Sayagi U Ba Khin and teachers within my own tradition, I think on this point may have been concocted as a result of misunderstanding, mistranslation or hagiography.

Webu Sayadaw, from his compilation of discourses in Way to Ultimate Calm, and from John Coleman's Quiet Mind was a life-long practitioner of the dhutanga of not ever lying down, not even to sleep. He did sleep, but did so the sitting position. That is not to say that he slept regularly nor that it may have been of an altogether different qualitative experience but sleep he did.
“No lists of things to be done. The day providential to itself. The hour. There is no later. This is later. All things of grace and beauty such that one holds them to one's heart have a common provenance in pain. Their birth in grief and ashes.”
- Cormac McCarthy, The Road
Learn this from the waters:
in mountain clefts and chasms,
loud gush the streamlets,
but great rivers flow silently.
