A satyagrahi is a person who has dedicated him- or herself to truth (sat, or satya), or more specifically one who offers satyagraha, or participates in a satyagraha campaign.

The requirements Gandhi laid down for his satyagrahis include:

• He or she has a firm commitment to nonviolence, simplicity, honesty, chastity, and self-discipline in thought, word, and deed.
• He or she holds firmly (the meaning of a-graha) to the truth, in particular to that all life is interconnected, rejecting violence in any form, including humiliation of opponents, accepting humiliation of oneself, or the violence toward oneself implied in the use of intoxicating substances.
• He or she is always ready to forgo material comforts for the greater good of all beings, relying always on soul-force when it is necessary to resist another’s behavior.

The satyagrahi must always exercise trust of the opponent (that is, trust that he or she can be awakened to compassion), and cultivate an unwavering faith in the goodness of humanity, constantly separating person from deed.
