Strict separation of mool-bera (immovable main murti) from utsava-bera (procession murti). Murti made of stone — never metal.

Smarta tradition (panchayatana puja) · स्मार्त पञ्चायतन पूजा
Deity: Five deities equally — Vishnu, Shiva, Devi, Surya, Ganesha (worshipped together)
Scriptural basis — Established by Adi Shankaracharya in the 8th C. Based on the smritis (hence "Smarta"). The panchayatana arrangement is described in Padma Purana + Skanda Purana.
Temples — All Smarta brahmana homes have a panchayatana arrangement of 5 deities. Many shankaracharya-affiliated temples follow Smarta panchayatana.
Features — The 5 deities are placed in a specific geometric pattern: one in the centre (varies by family ishta-devata), and the other 4 in the corners. Shankaracharya prescribed: Saiva-pradhana = Shiva centre; Vaishnava-pradhana = Vishnu centre, etc. All 5 worshipped daily with the same upacharas.
Initiation — No special diksha required for daily Smarta panchayatana puja — every Brahmana householder learns it through the upanayanam + family tradition.
Living lineage — 4 Shankaracharya mathas — Sringeri, Dwaraka, Puri, Jyotirmath, plus the Kamakoti Peetham (Kanchi). Most Smarta brahmanas (Iyer, Deshastha, Kannada Smarta, Nambudiri) follow this.
