Each sect/subsect within Hinduism has its own dedicated 'sectarian holy markings" known as Tilaka (तिलक).
The Śaivaites (शैव) - the worshippers of god Śiva as the Supreme, wears the Tripuṇḍra Tilaka (त्रिपुण्ड्र-तिलक).
The Śāktas (शाक्त) - the worshippers of the great goddess Parā-Śakti as the Supreme, wears a red dot (Bindu) as their Tilaka.
The Vaiṣṇavas (वैष्णव) - the worshipper of god Viṣṇu (or Kṛṣṇa or Rāma, etc.) as the Supreme, wears the Ūrdhvapuṇḍra Tilaka (ऊर्ध्वपुण्ड्र-तिलक) or it's sub-variations.
There are two other deities viz. Gaṇeśa & Sūrya with their own dedicated sects - Gāṇapatyas (गाणपत्य) and Sauras (सौर), respectively. Together these five deities form the part of the Pañcāyatana (पञ्चायतन) or Pañcāyatanapūjā form of worship, which is specifically observed by the followers of the Smārta tradition (स्मार्तधर्म).
In any case, the three out of the five deities of the Pañcāyatana - Śiva, Śakti & Viṣṇu have their own dedicated Tilakas for their sects.
Do the sects of the other two deities (Gaṇeśa & Sūrya) have their dedicated Tilakas?
What Tilakas do the Gāṇapatyas (गाणपत्य) and the Sauras (सौर) wear?
What is the name of Tilakas worn by the Gāṇapatyas and Sauras?
