Worship of Murti is valid in sanatan dharma? if yes then why yjurved said god has no shape in 32 :3?

Why there is MURTI POOJA (Idol Worship) in Hinduism?? This is Right or wrong??
Sanatan Dharma cannot be described in words, which cannot be confined to any boundary and which cannot be kept stagnant. It comprises of the oldest scriptures of the world, which have been guiding and nurturing people since centuries, and which would continue to do so till the presence of the mankind, through their ever evolving philosophies.

Unfortunately, there are a set of people who criticize certain practises associated with Hinduism, under the influence of their prejudices and biased views, and also on the basis of their limited knowledge of Hinduism. Murti Puja, which is better known as idol worship is one such Hindu practice, which is heavily criticized.

Argument against Icon worship:

Many people argue that the scriptures of Hinduism do not support idol worship. They quote incomplete verses from Vedas, Upanishads and Bhagavad Gita to prove their point, and to infuse confusion in the minds of the Hindus.

The most common verse used by the detractors of idol worship is :

"Andhatama pravishanti ye asambhuti mupaste"

The twisted explanation of this verse, which they give is as follows :

"They enter darkness, those who worship the natural elements" (Air, Water, Fire, etc.). "They sink deeper in darkness, those who worship sambhuti."

'Sambhuti', according to them means created things. For example table, chair, icon, etc. And hence, they claim that when Hindus worship icons, they go against their own scripture. However, truth is far from it. This is neither the correct verse nor the complete verse. Needless to say, one must never get judgemental on the basis of incorrect & incomplete information.

The correct and the complete verse from Isha Upanishad is as follows:

andham tamah pravisanti ye' sambhut imupasate,
tato bhuya iva te tamo ya u sambhutyam ratah.
(Isa Upanishad, verse no 12)

And the correct translation of the above mentioned verse is as follows:

Into blinding darkness enter those who worship the unmanifest (meaning hidden self, the non being , imagination etc), and into greater darkness those who worship manifest alone(meaning visible world,illusion,icons, material wealth etc) . He who understands both unmanifest and manifest together, crosses death through unmanifest and attains immortality through manifest.

Some other verses quoted by the detractors of idol worship to prove that god does not have any form, hence, he should not be worshipped in the form of idols, is as follows:

"Na tasya pratima asti"
There is no likeness of Him.
[Svetasvatara Upanishad; chapter 4:19]

"Na samdrse tisthati rupam asya, na caksusa pasyati kas canainam."
His form is not to be seen; no one sees Him with the eye.
[Svetasvatara Upanishad; chapter 4:20]

"na tasya pratima asti"
There is no image of Him.
[Yajurveda; chapter 32:3]

"shudhama poapvidham"
He is bodyless and pure.
[Yajurveda; chapter 40:8]

The Hindus do believe that god has no form. He is Nirakar (formless). However, we also believe that being the almighty, he is capable of taking any form. And he blesses his devotees through the form, in which the devotees worship him (Bhagwad Gita, Chapter 11). That is why we worship him in the form of idols. The verses from Svetavatara Upanishad to support this point:

"Subtler than the subtlest, stable in the midst of great confusion, the creator of all,bearing many forms, holding the entire universe in his embrace, when one knows him as the auspicious, a great peace shall descend upon him."
(Svetavatara Upanishad; chapter 4:14)

"You are woman. You are man. You are the son and also the daughter. As an old man you walk with a stick. being born you assume faces in many directions."
(Svetavatara Upanishad; chapter 4:3)

Thus, from the above mentioned verses we can conclude that god has no specific form, but he is capable of taking any form. Hence, there is nothing wrong in worshipping him in the form of idols.

Significance of idol worship:-

1.The idea behind idol worship is to promote harmony and brotherhood. Idols (murtis) are normally made of stone/iron or other hard objects, which is a reminder of the fact that, Hindus have such high respect for every creation of the god, that they worship even the hard objects created by him (such as stone, iron etc ) as the god himself. So one can just imagine the respect, which a Hindu will have for a human being, which is the supreme creation of the almighty.

2. Murti Puja is one of the core concepts of Sanatana Dharma. The literal meaning of murti is manifestation, something that has taken a concrete form. Murti without any prefix refers to devata murti or god-form. Thus murti is a representation (in a manifest, definite form) of god-form. Murti puja is worship of murti as a god-form, worship of god-form in the murti. The devotee worships the deity (or devata) who is requested to reside in the vigraha (murti) for the duration of the worship. A murti usually is a concrete shape, having features attributed to the god-form. These are usually the physical attributes of the deity as described by the theology for the Devata. The murti has as many hands/legs/heads as spoken of in theology. Features like wearing snakes/garlands/having moon as adornment, the weapons they hold, are also reflected in the murti.
