Turning The Wheel of Dharma ..whatever translation is in Goddard's A Buddhist Bible, that and Cutting Through Spiritual Materialism pretty much signed me up. Read them many years apart, I picked up A Buddhist Bible at 17 or something, and spent years just reading and rereading that Sutta over and over, it was the one that really spoke to me in the beginning, simple as it is. Years later I read Cutting Through as an adult, and it kind of put two and two together for me in some way.
"Just as a lotus does not grow out of a well-levelled soil but from the mire, in the same way the awakening mind
is not born in the hearts of disciples in whom the moisture of attachment has dried up. It grows instead in the hearts of ordinary sentient beings who possess in full the fetters of bondage." -Se Chilbu Choki Gyaltsen
