Correct. In fact, images, murtis, physical forms, idols, are actually sanctioned by Sri Krishna in the Bhagavad Gita 12.5:
For those whose minds are attached to the unmanifested, impersonal feature of the Supreme, advancement is very troublesome. To make progress in that discipline is always difficult for those who are embodied. Purport can be found here
Bhagavad Gita 12.5
Tl;dr... Being sensory beings, it is difficult for humans to connect with the unmanifest Supreme. We need to use our senses to experience anything, including God.
From a Catholic perspective, I find myself very much in agreement with you here!
The Catholic tradition is acutely aware of our sensory disposition, hence why our masses and devotional practices are characterised by elaborate "
smells and bells" ceremonies that aim to stimulate all five senses in worship.
Images depicting the divine or divinized, saintly individuals - whether statues, icons, paintings etc. - are an important element of this.
As the Catholic mystic and priest Blessed Jan van Ruysbroeck put it:
"...Certainly in this exercise a man should lay hold of good images to help him; such as the Passion of our Lord [crucifix] and all those things that may stir him to greater devotion. But in the possession of God, the man must sink down to that imageless Nudity which is God; and this is the first condition, and the foundation, of a spiritual life..."
Blessed John of Ruysbroeck (1293 - 1381), The Sparkling Stone
In other words, he's concurring with what you've just said: if I might paraphrase the Bhagavad Gita, to advance towards "
the unmanifested, impersonal feature of the Supreme" (the "
Imageless Nudity which is God" in Blessed Ruysbroeck's words) one must first "
lay hold of good images to help him".
Most Abrahamic traditions - Judaism, Islam, many forms of Protestant Christianity, Iconoclastic Orthodoxy and the Baha'i Faith - are against the idea that there ever can be "
good images" of the one incorporeal, inexpressible, almighty God who exceeds the grasp of all finite imagination, or even of saintly humans who reflected God in their earthly lives. We Catholics are the definite exception, for which reason - despite being the oldest Christian tradition along with Eastern Orthodoxy and Oriental Orthodoxy - we've found ourselves accused by other Christian sects, on occasion, of being "idolatrous". So, yeah, I
know how it feels to all you Hindus and Pagans and others out there
Our definition of "idolatry" is more liberal - but no less strict when it comes to what we'd view as constituting actual idolatry, I should reiterate.
But, you don't tend to see spectacles like this in other Abrahamic faiths:
