Answer in Details
According to Shaiva philosophy, everything in creation is the result of the harmonious union (reunion) of Shiva (pure consciousness) and Shakti (divine energy). This spiritual reunion is often symbolized by Ardhanarishvara, the half-Shiva, half-Parvati form, which demonstrates perfect balance and harmony between opposites.
On a personal spiritual level, harmonious reunion refers to the inner union of the devotee’s soul (Atman) with the Supreme Consciousness (Paramatman), which is Shiva. This is the ultimate goal of yogic and tantric practices: to dissolve the illusion of separation and realize oneness with Lord Shiva, resulting in peace, bliss, and liberation (moksha).
To achieve this harmonious reunion, Lord Shiva teaches the path of meditation, detachment, self-control, and devotion. Through these practices, one can transcend duality and experience the divine harmony that is the true nature of existence.
