Answer
At the heart of major religions lies compassion, a unifying thread that transcends cultural and theological boundaries. According to Karen Armstrong, this shared principle inspires love, kindness, and understanding, forming the bedrock of ethical and moral teachings. From Christianity's emphasis on selflessness to Buddhism's focus on alleviating suffering, compassion emerges as the common denominator that binds diverse religious traditions together, guiding individuals toward spiritual fulfillment and harmonious coexistence.
