Deity-epithet name for Anurādhā, whose divinity is Mitra. Used at SS 9.14 and also by Brahmagupta at Bhagrahayutyadhikāra 9 (maitrasya) in the yogatārā table, so the usage is standard across the siddhāntas rather than peculiar to one text. The Buddhist Śārdūlakarṇāvadāna independently gives Anurādhā the deity Mitra.

The database currently carries Maitra only from the later siddhāntas and al-Bīrūnī; this pushes the attestation back by many centuries. As with Aindra, the epic makes the identification internally: 'Mars, having gone retrograde in Jyeṣṭhā, presses towards ANURĀDHĀ, as if pacifying the MAITRA' — anurādhāṃ and maitraṃ are in apposition in the same half-verse. Mitra is Anurādhā's presiding deity in every nakṣatra-devatā list. δ Sco is imported from the Sūrya Siddhānta entry. A late appendix passage in the Anuśāsana Parva (13,111.021d appendix 012A, a nakṣatra-puruṣa scheme assigning each asterism to a limb) also uses the simple form 'mitra' as an asterism name, but it is an interpolated passage and is noted rather than relied on.
