廬山蓮宗寶鑑 1.71

1.71

夫大乘玄要，元不離於一心；淨業正因，必先修於十善。斷身口七重之罪，七行斯成；滅意識三毒之根，三學自備。彌陀經內求淨土者之所當修，華嚴經中離垢地者乃能親證。人天至於有頂，以十善為受生之緣；聲聞以至佛乘，由十善為入道之本。弗遵佛制，墮三塗之要門；縱得人身，獲二種之惡報。不修乃十不善道，奉持為十戒法門，實乃淨土鎡基，普勸常修此行，是菩薩之法苑，宜令安住其中，可以至無畏大城、可以登不退轉地，功德詎可思量？佛子所以當學。

The profound essence of the Great Vehicle is originally never separate from the one mind; the correct cause of pure karma must first be the cultivation of the ten wholesome actions. By severing the seven grave offenses of body and speech, the seven practices are accomplished; by extinguishing the roots of the three poisons in the mental consciousness, the three trainings are naturally complete. This is what those seeking the Pure Land in the Amitābha-sūtra ought to cultivate, and what those on the Immaculate Ground in the Avataṃsaka-sūtra personally realize. Gods and humans up to the Peak of Existence take the ten wholesome actions as the condition for rebirth; śrāvakas up to the Buddha Vehicle rely on the ten wholesome actions as the root of entering the Way. Not complying with the Buddha's regulation is the prime gate to falling into the three wretched paths; even if one attains a human body, one receives two kinds of evil retribution. Not cultivating them constitutes the ten unwholesome paths; upholding them constitutes the Dharma-gate of the ten precepts. Truly they are the foundation of the Pure Land; we universally encourage constant cultivation of this practice. It is the garden of the Dharma for bodhisattvas, wherein they should dwell peacefully; through it one can reach the great city of fearlessness, and mount the stage of non-retrogression. How could its merit be conceived? This is why Buddhist disciples ought to study it.
