Siva

Siva is power of God(Shakti), will power of god, command of God. In Gurbani, Siv is treated as God, and his Sakat(i) is named as Shiva by Guru Gobind Singh. Shiva is equivalent to Chandi i.e Gurmat.

Gurbani said

• ਸਿਵ, ਸਕਤਿ ਆਪਿ ਉਪਾਇ ਕੈ ਕਰਤਾ ਆਪੇ ਹ੝ਕਮ੝ ਵਰਤਾਝ : Means Siv = God = Karta himself give birth to Sakti = Hukam = Siva.
• ਗ੝ਰਮ੝ਖਿ ਜੋਤਿ ਭਲੀ ਸਿਵ ਨੀਕੀ ਆਨਿ ਪਾਨੀ ਸਕਤਿ ਭਰੀਜੈ : Gurmukh is itself Jyot of Siv = God, and Sakti = Command = Siva, always favours him.

Guru Gobind Singh gave that Sakti of Siv = Shiva. He said ਦੇਹ ਸਿਵਾ ਬਰ੝ ਮੋਹਿ ਇਹੈ ਸ੝ਭ ਕਰਮਨ ਤੇ ਕਬਹੂੰ ਨ ਟਰੋਂ ॥. Goabind Singh as a devotee is asking Siva = Hukam = Shakti of God to help him so that he may not hesitate from performing good actions.
