Causal Ground; 因地; Tibetan: རྒྱུའི་ས (gyü-sa); Wylie: rgyu’i sa; Sanskrit: hetu-bhūmi;
Causal Ground refers to the stage of spiritual practice before the final attainment of Buddhahood, during which a practitioner cultivates the causes and conditions that will lead to awakening. It encompasses the entire bodhisattva path, from the initial generation of bodhicitta through the ten grounds of realization. At this stage, the practitioner is actively accumulating merit and wisdom, purifying defilements, and perfecting the six perfections. The distinction between the causal ground and the resultant ground is fundamental to the Mahayana path, with the former representing the process of training and transformation, and the latter representing the final fruition of Buddhahood.

因地指修行者尚未成佛之前的修行階段，在此階段中廣修一切善法，累積成佛的因緣條件。涵蓋從初發菩提心直至十地圓滿的整個菩薩修行歷程。在此階段中，修行者積極累積福德與智慧二種資糧，淨除煩惱障與所知障，圓滿六度萬行。因地與果地的區分，是大乘佛法中極為重要的概念框架，因是修行用功的過程，果則是究竟圓滿的佛果。
