Adi Shankara,
The Crest Jewel of Wisdom — Introductory by Charles Johnston
(1946)
“ But the other part of Śankara's work, the manuals and catechisms for learners, are complete and perfect. They really teach, quite plainly and lucidly, the first steps on the path of wisdom; they point out, with clear insistence, the qualities that are necessary to make these first steps fruitful; qualities without which the learner may remain, hesitating and halting, on the threshold, through lack of the force and sterling moral worth which alone make any further progress possible. ”
