Yes, but there is a key difference. The ritual invokes the actual presence of God, in mystic Hinduism. Actual inner beings (spirits) show up, to help with prayers or unseen blessings. The ritual is very far from being empty. But I wouldn't expect you to understand this either as It's an experience. So it's like a morning exercise, stretching is good for the physical body, the sadhana/puja is good for the soul body. Hindus believe we have to feed the soul body as well.
I understand you feel you need the ritual.
I ask if you are persecuted for your faith, are deprived of all you own, thrown in a cell with nothing but you, do you think you prayer would suffer because you have no objects to help in that prayer but your heart to offer it?
The same with Holy Communion in some branches of Christianity. They say they must partake of a piece of bread and a drink of grape juice for the prayer to be meaningful, wheras many other Christians do not use outward symbols.
So My thoughtss are the soul does not partake of material substance, but you would know this, as none of it what is presented would diminish. The soul is far removed from this world and when we attach our selves to this world, we have lost our connection to our own soul.
Challenging thoughts is what God always offers us.
