teresa is on this shelf because she lived the numbness in the most literal way possible: she was a nun whose prayer went dead for nearly two decades, and instead of hiding it she wrote it down in exact detail for anyone who'd recognise it.
she entered the convent of the incarnation in ávila in 1534, at nineteen. an early near-fatal illness with a stretch of paralysis. and then, in her own count, 'eight-and-twenty years' as a nun before her real turn, more than eighteen of them a running battle between wanting god and wanting the world — 'nearly twenty years on this stormy sea, falling and rising, but rising to no good purpose'.
what makes her useful is how concrete she is about hollow practice. she never stopped mental prayer — she later says that's the one thing that saved her — but it had gone empty. she describes being more occupied with wanting the appointed prayer time to be over, and watching the hourglass, than with anything good. she dreaded the room: 'the sadness i felt on entering the oratory was so great, that it required all the courage i had to force myself in'. and she names the split — in the world she was sad remembering what she owed god; in prayer, her worldly attachments disturbed her. at peace nowhere. she doesn't blame it all on god's absence, either; she owns the friendships and distractions that pulled against her.
the turn came around 1554, at about 39, and it wasn't from trying harder. a statue of christ, sorely wounded, had been brought into the convent for a feast. she saw it and was struck to the heart, wept, and something changed that didn't change back. from there her prayer became the ground of everything: the reform of the carmelites, seventeen convents starting with st joseph's in 1562, the interior castle (1577) — her map of the self as a castle you move inward through, room by room, whatever the weather in any one room.
honest notes: she never rewrites the dry years as a mistake. later came visions (from 1559), which the church investigated, and in 1576–79 real institutional persecution and an inquisition inquiry — she wasn't done with hard seasons. quotes are the david lewis translation of the life. and the line about christ having no body now but yours — hung on her everywhere — isn't in anything she wrote.
