According to Christopher Titmuss

The beneficial influence of the Buddha falls into three primary areas: non harming, meditation and wisdom. By taking apt quotations from the vast number of talks (over 10,000) which the Buddha gave during his 45 years of teaching, Titmuss offers one thought-provoking excerpt for each day of the year - and so helps illuminate these three important themes.

This is a book readers will want to keep for many years, and dip into time and again.
