Thus, the idol with divinity which we see in our temples is an object of beauty for us, and worthy of meditation. If our thoughts are of a high order, then we worship the deity in the above manner, so that we may get supreme happiness. It is with this idea that we perform abhisheka and decorate the idol with ornaments etc. Thus we worship God in these various ways by doing so many upacharas. This kind of worship is possible only in the Hindu religion.
Idol worship is very important in our religion, for the ordinary people.
When we bow before an idol or pray before the deity consecrated in the idol, we never think that it is only a piece of stone, but we think that the deity in the idol is the protector and the root cause of the whole world. Thus, temples help to increase the devotion of a person to God and this devotion helps him to overcome or reduce his sufferings. Ordinary people may not have the capacity, and strength of mind to bear their sufferings. But with bhakti or devotion to Ishwara, they can face them, and get also the mental strength to bear them. It is for this purpose that an ordinary person goes to the temple.
