Shiva is considered the Absolute Lord and his power is represented by Shakti, Durga, Kali and Mother. Durga is identified as the energy aspect of Shiva. Without Durga, Shiva has no expression and without Shiva, Durga has no existence. Shiva is the soul of Durga. Durga and Shiva are identical.
Shiva is only a silent witness. He is motionless, impersonal, inactive. He is not affected by the cosmic play. Durga does everything. Shiva is omnipotent. He is pure consciousness. Shakti is dynamic and the power of Shiva is Shakti. Shakti is the power that is latent in the pure consciousness. Shakti is inherent in God. You cannot separate heat from fire, so you cannot separate Shakti from Shiva. Shiva and Shakti are inseparable. Worship of Mother means worship of Shiva.
Love in the heart connects with the divine within and with the divine externally. Shiva and Shakti represents this divinity. They both are forgiving and quick in their blessings. They have no expectations from us, only to be karma yogis and practice swadhyaya (self -study and introspection). Try to be constantly aware of how you behave and this will enable you lead a spiritual and creative life.
