Samadhi (in Jainism) generally means a deep, focused absorption of the mind (mental stillness) and is closely linked to the practice of equanimity.

• In Shvetambar tradition, the idea of Samadhi is connected with disciplined meditation and the broader practice of samayika (meditative/4‑8 days of ritual equanimity). The common everyday version students and lay followers study is how to perform samayik as a 48‑minute practice to remain as the pure self and cultivate equanimity.

• There is also an important related concept in Jain practice called samadhi-maran (the peaceful death through sallekhana). In Shvetambar and Digambar sources, sallekhana is described as a deliberate, prepared cessation of life with spiritual focus, not an act of impulsive suicide. This is often discussed in the same breath as the idea of attaining a calm, conscious exit from the body.

Note: If you are comparing Digambar and Shvetambar interpretations, both traditions honor Samadhi as deep mental absorption and disciplined practice, but the practical expressions (like how samayika is observed, and the role of sallekhana) have tradition-specific details. The core aim remains purification of the soul and progress toward liberation.
