Tirthankara sects of Jainism Digambara and Svetambara have different depiction of idols. Digambara images are naked without any beautification whereas Svetambara ones are clothed and decorated with temporary ornaments. The images are often marked with Srivatsa on the chest and Tilaka on fore head. Srivatsa is one of the ashtamangala (auspicious symbol). It can look somewhat like a fleur-de-lis, an endless knot, a flower or diamond-shaped symbol. The first "Tirthankara", "Rishabhanatha" is mentioned in Hindu texts like the "Rigveda", "Vishnupurana" and "Bhagwata Purana". The Yajurveda mentions the name of three Tīrthaṅkaras – Ṛiṣhabha, Ajitnātha and Ariṣṭanemi. The Bhāgavata Purāṇa includes legends
Digambara texts such as the "Samayasāra" and the "Pravacanasāra". Other prominent "Acharyas" of this tradition were, Virasena (author of a commentary on the "Dhavala"), Samantabhadra and Siddhasena Divakara. The "Satkhandagama" and "Kasayapahuda" have major significance in the "Digambara" tradition. Relics found from Harrapan excavations such as seals depicting "Kayotsarga" posture, idols in "Padmasana" and a nude bust of red limestone, give insight into the antiquity of the "Digambara" tradition. The presence of gymnosophists (naked philosophers) in Greek records as early as the fourth century BC, supports the claim of the "Digambaras" that they have preserved the ancient "Śramaṇa" practice.
