The term Upanishad (upa-ni-shad) means to sit down near, capturing the essence of learning and spiritual growth in the presence of a teacher. With over 200 Upanishads known, many have faded from history, surviving only through references in other texts. These profound teachings were traditionally kept secret and transmitted orally as Shlokas, a revered poetic form from the Vedic tradition. The terms Maitra (मैत्र) and Maitri (मैत्री) embody kindness, goodwill, and universal friendship. The Maitrayaniya Upanishad, linked to the Maitrayanas school of the Yajurveda, explores deep metaphysical questions about the Atman (Self, Soul) and is organized into seven Prapathakas (lessons). Likely composed in the late 1st millennium BCE, this Upanishad is among the 11 classical texts that inform Sankaras esteemed commentary on the Vedanta-Sutras, alongside notable works like Chandogya and Brihadaranyaka. The teachings of the Upanishads transcend religious boundaries, offering timeless philosophical insights. German philosopher Arthur Schopenhauer praised these texts as the peak of human wisdom.
