Final answer:
The karmic cause of the human realm revolves around the principle of karma, which governs the cycle of samsara based on an individual's actions in their lifetime. Positive karma furthers the soul towards moksha, suggesting a divine order underlying the karmic system.
Step-by-step explanation:
The karmic cause of the human realm is deeply rooted in the concept of karma, an intrinsic principle in Hinduism and Buddhism. Karma refers to the spiritual principle of cause and effect, where an individual's words, actions, and deeds within one lifetime influence their conditions in the subsequent life cycles. A person's karma determines the soul's journey through samsara, the cycle of death and rebirth, influencing the level or form of their next incarnation. Positive actions and adherence to dharma result in a positive karmic residue, drawing the soul closer to moksha, the ultimate liberation from the cycle of rebirth. The intricately ordered nature of how karma dispenses justice or karmic appropriateness suggests the existence of a divine force or entity responsible for maintaining this balance within the cosmos.
