Do not limit your faith to only idols.
We all worship our favorite God and believe that they will always keep the grace on us. We have created different forms of our God and have given that a form of an idol and over a long time we have an attachment to God in the same idol form.It is a good thing that we go to the temple, pray for idols, get them in our house as well. All these actions are good ways for our mental peace. But the problem comes when the value or importance of the idol exceeds your faith, and you are not able to worship God if the idol is not there. I have seen many people who worship by the rule but they need an idol or a statue of God or a photo of God to worship them.
If you have faith in your mind then you do not need any idol, statue, or photo. You can connect with your God from any place at any stage and join them, this is true devotion.
