The Principal Upanishads: Vedantic Inquiries
The summit of direct spiritual realization and the Mahavakyas
ॐ पूर्णमदः पूर्णमिदं पूर्णात्पूर्णमुदच्यते । पूर्णस्य पूर्णमादाय पूर्णमेवावशिष्यते ॥ ॐ शान्तिः शान्तिः शान्तिः ॥
oṁ pūrṇamadaḥ pūrṇamidaṁ pūrṇātpūrṇamudacyate | pūrṇasya pūrṇamādāya pūrṇamevāvaśiṣyate || oṁ śāntiḥ śāntiḥ śāntiḥ ||
“Om, That is Whole; This is Whole; from the Whole emerges the Whole; taking the Whole from the Whole, the Whole alone remains. Om Peace, Peace, Peace.”
आरम्भो ज्ञानस्य दीपः — Every journey begins with a quiet breath of inquiry.
Philosophical Objective & Scope
The Upanishads (meaning "sitting near the teacher with reverent attention") represent Jnana Kanda—the philosophical crown of the Vedas. Here ritual yields to contemplative inquiry into the ultimate nature of Reality (Brahman), the Self (Atman), and the dissolution of existential duality.
Scholarly Lineage & Canonical Context
Of the 108 canonical Upanishads listed in the Muktika canon, 10 are revered as the primary (Mukhya) Upanishads: Isha, Kena, Katha, Prashna, Mundaka, Mandukya, Taittiriya, Aitareya, Chandogya, and Brihadaranyaka.
