Shaiva Siddhanta and Kashmir Shaivism share a common reverence for Shiva, yet they journey down very different paths.

Metaphysics
• Shaiva Siddhanta (mainly in Tamil Nadu) upholds a “qualified dualism.” Shiva, souls (pashus) and the world (pasha) coexist as distinct realities. Liberation means the soul becomes ever-pleasing to Shiva, but never totally loses its individual flavor.
• Kashmir Shaivism (rooted in Kashmir’s tantric schools) embraces absolute non-dualism. Everything—mind, cosmos, deities—manifests as Shiva’s own self-expression. Liberation simply reveals what was already true: consciousness is one seamless reality.

Authority and Epistemology
• Siddhanta leans heavily on Agamas, Vedas and orally transmitted Tamil hymns (Tevaram, Tirumurai). Scripture, temple rituals and a guru’s blessings form the backbone of knowing.
• Kashmir Shaivism adds pratyaksha (direct perception) and anumana (logical inference) to its toolkit, but its real MVP is recognition (pratyabhijna). A sudden “aha” moment—often sparked in meditation or mantra—uncovers one’s identity with universal consciousness.

Ritual and Practice
• South Indian Shaiva temples sparkle with fire ceremonies, elaborate pujas and communal bhajans. Devotees follow a well-marked ritual calendar, year in, year out.
• Kashmir Shaivism tends to pull the rug out from under rigid forms. Sadhana happens internally: mantra japa, breath awareness, vessel-shaking visualizations (chakras). Workshops in Rishikesh and even online satsangs today brim with its spontaneous, heart-centered techniques.

Role of Shakti
• In Siddhanta, Shakti is Shiva’s devoted energy, assisting from “outside” until liberation.
• In Kashmir Shaivism, Shakti and Shiva dance as inseparable partners—Shakti isn’t just Shiva’s power; she’s his very essence.

This divergence still ripples through India’s spiritual landscape. Temple festivals in Madurai attract thousands with centuries-old chants, while contemporary retreats inspired by Abhinavagupta’s writings draw seekers eager to taste non-dual awareness. Such a contrast proves there’s more than one road up Mount Kailash.
