Offering Naivedya to Lord Shiva

According to Shiva Puran

• A devotee gets liberated from all of his sins merely at the sight of the Naivedya, which has been offered to Lord Shiva. 
• He attains great virtues by having the Prasada."
• A man must not accept the Prasada if the worship has been done under the supervision of a 'Chandala', but some of the Shivalingas like Baanlinga, Siddhalinga, and Swayambhu Linga are exceptions to this rule. 
• The Prasada which has been offered to the Shivalinga and remains lying on it is prohibited from having, but the prasad which is not touching the Shivalinga should be accepted.
