Lord Shiva is considered to be the destroyer of the world. Shiva is one of the most popular gods of the Hindu religion. Shiva is also a kind-hearted god who blesses people. Following is the Shloka for invoking Lord Shiva:

"Kailaasarana Shiva Chandramouli
Phaneendra Maathaa Mukutee Zalaalee
Kaarunya Sindhu Bhava Dukha Haaree
Thujaveena Shambho Maja Kona Taaree"

Meaning: Lord Shiva is seated on Mount Kailash; his forehead is decked with the moon and the king of serpents as a crown. The lord is full of compassion and the remover of illusion. Shiva is the only protector. I surrender myself to such great Lord Shiv-Shankar.
