Is it necessary to be religious to be a Buddhist?
The answer is no, as the definition of "being religious" varies for each individual. Some may have reservations due to negative experiences with their previous religion, associating it with blind adherence to dogmas and traditions.
Buddhism, however, encourages a different approach. The Buddha himself urged his followers to personally test his teachings. In the Kalama Sutta, he advised people not to believe blindly in traditions or dogmas but to put his teachings into practice and observe their effects on their own lives. Moreover, he recommended comparing personal findings with the experiences of wise and honorable individuals.
By following this path, practitioners arrive at their own authentic understanding of Buddhist teachings. Whether one labels it as religion, spirituality, or philosophy is less important than the practical application of these principles in daily life. The Buddha emphasized that one's actions and the consequences of those actions hold greater significance than mere labels.
