Final answer:
The Upanishads, part of the larger corpus of the Vedas, address the issues concerning reincarnation and the path to liberation (moksha) from the cycle of samsara.
Step-by-step explanation:
The correct option : c
The Upanishads are a part of the Vedas and are one of the primary sources of Hindu spiritual philosophy. They are a collection of texts that offer deeply philosophical and esoteric teachings. The term Upanishad is derived from the Sanskrit words 'upa' (near), 'ni' (down), and 'shad' (to sit), suggesting the manner in which these teachings were historically imparted - with students sitting close to the teacher to receive knowledge. Composed between 800 and 200 BCE, these texts embody the Vedic understanding of the nature of reality, the self, and the universe.
The Upanishads discuss samsara, the cycle of birth, death, and rebirth, extensively. They also introduce the concept of moksha, which is liberation from this cycle, achieved through knowledge (jnana), devotion (bhakti), or righteous action (karma). This profound knowledge serves as a means to realize the inner self (Atman) and its unity with the ultimate reality, the Brahman, thus offering a path to escape reincarnation. The Bhagavad Gita, which is part of the epic Mahabharata, is also considered a key Upanishad and further elaborates on these themes within the context of a dialogue between the prince Arjuna and the deity Krishna.
