Ṛṣabha(Rishabha) was born as a partial incarnation of God Viṣṇu(Vishnu) , in the lineage of Agnīdhra (Agnidhra), king of Jamvudvīpa (Jamvudwipa). Antarīkṣa was one of the sons sired by Ṛṣabha, and born of the womb of Jayantī (Jayanti). He was the younger brother of Rājarṣi (Rajarshi; a king wth the attributes of a sage) Bharata. Antarīkṣa and his nine brothers left the life of a householder and dedicated themselves to the worship of the Supreme Divinity.
From the eleventh section of Bhāgavatapurāṇa (Bhagavatapurana), it is known that Antarīkṣa (Antariksha)was one of those who were able to realise the Brahman. According to some rules of grammar, the dhātu (dhatu; root-verb) ‘īkṣ’ is read with small ‘i’, so the reading ‘Antarikṣa’ is also valid.
