  Consider this passage from the Kalimāt (Pourjavady &amp; Schmidtke 2006, 158, author’s translation): “If, however, a weakening of the bodily impediments were to be joined to the strength of the soul, whether this [strength] be original [asli, here meaning ‘inborn’] or acquired, the way the soul is strengthened by practice or the training that is associated with ‘those who know’ [i.e., the Sufis], then the bond is made firm in such a way that the soul will attain many hidden things, copious items of knowledge, and illuminative pleasures, whose true nature can be apprehended only by someone who has found them himself.” A few lines down tajriba is mentioned: “Many wonderful things of the souls are known by means of repeated experiences (tajarib), repetition, and some form of reasoning (qiyas).”
