Describing about meditation Vayudeva told the sages that to concentrate one’s restless mind during meditative state, a man needs some kind of form (Swarupa) or appearance. Idol worship is very helpful in this regard. If an idol of the deity is worshipped with full devotion, then a time comes when a man can have its sight even in an empty space. Idol worship also helps a devotee to reach towards the almighty God, who is formless. It is easy for a devotee who believes in
‘Sakar’ (with form) to change over to the Nirakar (formless) worship of God. But it is very difficult for a devotee who believes in the formless almighty to switch over to Sakar mode of worship. The knowledge of Shiva’s essence is a must attain salvation in both the modes of devotion.
