The Tzu Chi Foundation, a prominent Buddhist humanitarian organization, has seen a significant rise in women's involvement in its philanthropic activities in Indonesia. This study investigates the factors motivating women to actively participate in the Foundation’s charitable initiatives. Through in-depth interviews with female members, it highlights charismatic leadership as a key influence. Leaders known for their compassion, vision, and personal connection-building foster an environment that nurtures altruistic values and inspires women to engage in humanitarian efforts. These leaders empower women by instilling a strong sense of purpose and making them feel valued in their contributions. Altruism also emerges as a primary motivator, as Tzu Chi’s focus on compassion, selflessness, and service deeply resonates with its female members, providing them with a meaningful avenue for action. The study offers valuable insights into the drivers of women’s philanthropic engagement and provides strategies for organizations to enhance female participation in charitable activities.
