Anurādhā (Anuradha) is the seventeenth nakṣatra (nakshatra; star), a follower of Viśākhā (Visakha) nakṣatra. Anurādhā belongs to a constellation consisting of seven stars, looking like a serpent, and its presiding deity is Mitra (the Sun-god). In a śloka (sloka; verse) of Koṣṭhīpradīpa (Koshthipradipa), it is said that if a person is born under the influence of Anurādhā, he is is blessed with good achievements and a fair complexion. He becomes a conqueror of enemies, and well-versed in artistic activities. However, an ill-position of this nakṣatra can be harmful —
satkīrtikāntiśca sadotsavaḥ syāj
jetā ripūṇāñca kalāpravīṇaḥ.
syāt sambhave yasya kilānurāgaḥ
sampat pramādau ca vividhau ca syātam.
In Udyogaparva of Mahābhārata (Mahabharata), while conversing with Kṛṣṇa (Krishna), Karṇa (Karna) says, anticipating the terrible result of the war -Maṅgala ( the Mars), staying with the Jyeṣṭhā (Jyestha) nakṣatra, becomes ‘vakrī’ (vakri; antagonistic or hostile according to astrological terms), and it seems to be praying to Anurādhā to be added to Mitradevatā (the deity Mitra or Sun) . Siddhāntavāgīśa (Siddhantavagisha) has explained the deeper meaning of this — it gives an indication that the blessed Brāhmaṇa (Brahmana) Droṇa (Drona) has become vakra or hostile to the eldest of the Kaurava, Duryodhana, and adds his friendly wishes to the Pāṇḍavas, which will be fatal for Duryodhana. And Nīlakaṇṭha (Nilakantha) writes — if Maṅgala, staying in Jyeṣṭhā nakṣtra, becomes vakrī, that will suggest that Dhṛtarāṣṭra’s friends will be destroyed.

If one keeps a fast under the Anurādhā nakṣatra, and donates clothes and food to people, he attains the heavenly abode for hundreds of yuga(s). And by performing the śrāddha (sraddha; rites dedicated to the deceased spirit) rituals under the Anurādhā nakṣatra, one achieves a kingdom.
