Humanistic Buddhism approaches other religions with an inclusive and non‑exclusive spirit, grounded in compassion and concern for human welfare. Rather than claiming a monopoly on truth, it recognizes that different faiths respond to diverse cultural conditions and spiritual needs, and that many contain genuine wisdom, ethical insight, and a commitment to alleviating suffering. This outlook resonates with the Mahāyāna idea that multiple teachings can serve as skillful means for guiding beings according to their capacities. In this sense, other religions are not seen as rivals to be refuted, but as fellow travelers engaged in the shared task of nurturing human dignity and inner transformation.

From this perspective, Humanistic Buddhism emphasizes the ethical common ground it shares with other traditions. Values such as compassion, non‑violence, altruism, service to humanity, and responsible care for the world are understood as universal, not the property of any single religion. On that basis, it encourages cooperation in charity, peace‑building, education, and environmental protection, rather than competition for followers or influence. This shared moral horizon allows Humanistic Buddhism to participate in interreligious efforts that aim to reduce suffering and promote well‑being in concrete, socially engaged ways.

Interfaith dialogue holds a central place in this relationship. Humanistic Buddhist leaders and institutions actively seek conversation and collaboration with a wide range of religious communities, viewing them as partners from whom much can be learned, including approaches to social service, community organization, and moral education. At the same time, they offer distinctly Buddhist perspectives—such as mindfulness, non‑attachment, and the cultivation of inner peace—as contributions to a broader spiritual conversation. This dialogical stance is framed by a respect for religious freedom and pluralism, affirming that multiple faiths can coexist peacefully and fruitfully within the same society.

Despite this openness, Humanistic Buddhism maintains a clear Buddhist identity rooted in the Buddha, the Dharma, the Saṅgha, and the path of liberation. It tends to downplay sectarian disputes, both among Buddhist schools and between Buddhism and other religions, in favor of asking how any teaching can help reduce suffering here and now. In some cultural contexts, it also harmonizes with indigenous traditions such as Confucianism and Taoism, regarding them as complementary sources of ethical and philosophical insight rather than as competing systems. The overall orientation is one of ethical alliance and mutual respect, where distinct traditions stand side by side, each contributing its strengths to the shared work of benefiting the world.
