Moksha is a central concept in Hinduism, signifying liberation from the cycle of birth, death, and rebirth (samsara). It represents the ultimate goal of human life, transcending the material existence and achieving unity with the divine. This liberation is intertwined with the four purusarthas, where moksha serves as the final aim, guiding individuals towards spiritual fulfillment beyond worldly pursuits like dharma (righteousness), artha (wealth), and kama (pleasure).
