The life of Marichi is known more by the account of his descendants, notably by the works of sage Kashyapa. Marichi is then married to Kala and gave birth to Kashyapa (Kashyapa is also sometimes acknowledged as a Prajapati, who has inherited the right of creation from his father). He is believed to be formed out of the sustained energy of the Hindu god Vishnu. He is believed to have officiated the penance of Brahma at Pushkar, found in modern-day Rajasthan. He is also believed to have visited Bhishma during Mahabharatha, when he was lying on the arrow bed. Marichi is also quoted as the adviser of young Dhruva to pursue austerities. His name is featured in multiple Hindu scriptures like Brahmanda Purana and the Vedas.
