Ουπανισάδες (Spirituality) refers to a collection of ancient Indian texts that form the philosophical basis of Hinduism. These texts, composed in Sanskrit, explore profound questions about the nature of reality, the self, and the universe. They emphasize the importance of meditation, self-realization, and understanding the ultimate truth, known as Brahman. The teachings of the ουπανισάδες encourage individuals to seek inner knowledge and connect with the divine. They discuss concepts such as Atman (the individual soul) and its relationship to Brahman, promoting the idea that realizing this connection leads to spiritual liberation, or Moksha.
