Why do Hindus worship mūrtis (idols)?

the mūrti is not “just stone” to the devotee — it is a consecrated form through which the formless God is approached with love.

Hindu thought accepts that God is beyond all form (nirguṇa) and also that God can take form (saguṇa) out of love for devotees. Most human beings find it hard to love or focus on something with no shape at all. The Gītā itself says the path of the unmanifest is harder for embodied beings. A mūrti gives the heart and mind a place to rest.

In temples, a mūrti is installed through prāṇa-pratiṣṭhā, a rite inviting the divine presence to dwell in it. From then on it is treated as a living presence: woken, bathed, dressed, fed and put to rest. At home, a picture or small mūrti serves the same purpose more simply.

The word “idol” can mislead. The devotee does not worship the material; they worship God through it, much as a letter from a loved one is cherished not for its paper. Some traditions prefer a symbol like the liṅga or śālagrāma, or worship without images at all — all are respected paths.
