Within Sant Mat, the way one lives is regarded as inseparable from the inner practice of light and sound. The tradition generally calls for a lacto‑vegetarian diet, which excludes meat, fish, poultry, and eggs, while allowing dairy products. Alcohol and other intoxicating or recreational drugs are to be avoided, since they are understood to cloud awareness and interfere with meditation. There is also an emphasis on simple, pure foods, reflecting the broader ideal of a life that is calm, clear, and ethically grounded. Across lineages, the core dietary principles remain consistent, even though minor details may vary.

Lifestyle guidelines are framed as supports for spiritual practice rather than as mere external rules. Practitioners are encouraged to live morally, cultivating truthfulness, non‑violence, and purity in thought, word, and deed. Celibacy is expected for those who are unmarried, while fidelity is required within marriage, and livelihood is to be earned through honest means that do not involve harm or deception. Tobacco and other harmful substances are discouraged, as is excessive involvement in pursuits that strengthen attachment and distraction. The overall orientation is toward simple, moderate living, with regular meditation—often for several hours daily—and participation in satsang or spiritual gatherings. These disciplines are regarded as essential conditions that make the inner journey of Sant Mat genuinely effective.
