Why did the Buddha lay emphasis on conduct and values?

The correct option is For the overall well-being of humans.

The teachings of Gautama Buddha, central to Buddhism, place a profound emphasis on ethical conduct (Sila) and moral values. The primary objective of these teachings is the eradication of human suffering (dukkha) and the promotion of universal peace and happiness. Buddha did not focus on metaphysical speculations or rituals; instead, he directed attention toward practical, everyday living.

By advocating for right action, right speech, and right livelihood, Buddha sought to guide individuals toward a path that minimizes conflict and suffering. When individuals practice compassion, non-violence, and mindfulness, it leads to personal peace and collective harmony. Therefore, the core purpose of emphasizing conduct and values is to ensure the overall physical, mental, and spiritual well-being of all human beings.
