Bhrigu (Sanskrit: भृगु, IAST: Bhṛgu) is a rishi in Hindu tradition. He is one of the seven great sages, the Saptarshis, and one of the many Prajapatis (the facilitators of creation) created by Brahma. He was the first compiler of predictive astrology and also the author of Bhrigu Samhita, an astrological (jyotisha) classic. Bhrigu is considered a manasaputra ("mind-born son") of Brahma. The adjectival form of the name, Bhārgava, is used to refer to the descendants and the school of Bhrigu. According to Manusmriti, Bhrigu was a compatriot and companion of Svāyambhuva Manu, the progenitor of humanity. Along with Manu, Bhrigu made important contributions to the Manusmṛti, which was constituted out of a sermon to a congregation of saints in the state of Brahmavarta, after the great floods in this area. As per the Skanda Purana, Bhrigu migrated to Bhrigukaccha, modern Bharuch, on the banks of the Narmada river in Gujarat, leaving his son Chyavana at Dhosi Hill.

According to Bhagavata Purana, he was married to Khyati, one of the nine daughters of Prajāpati Kardama. She was the mother of Lakshmi as Bhargavi. They also had two sons named Dhata and Vidhata. He had one more son with Kavyamata, who is better known than Bhrigu himself – Shukra, learned sage and guru of the asuras. The sage Chyavana is also said to be his son with Puloma, as is the folk hero Mrikanda. [Maha:1.5] One of his descendants was sage Jamadagni, who in turn was the father of sage Parashurama, considered an avatar of Vishnu.

Bhṛgu is mentioned in the Shiva Purana and the Vayu Purana, where he is shown present during the great yajna of Daksha (his father-in-law). He supports the continuation of the Daksha yajna even after being warned that without an offering for Shiva, it was asking for a catastrophe for everyone present there. In the Tattiriya Upanishad, he is described to have had a conversation with his father Varuni on Brahman.

In the Bhagavad Gita, Krishna says that among sages, Bhrigu is the representative of the opulence of God.

The Bhagavata Purana describes a legend in which sages gathered at the bank of the river Sarasvati to participate in a great yajna. The gathered sages could not decide who among the Trimurti (supreme trinity) of Brahma, Vishnu, and Shiva was pre-eminent and should be the recipient of the yajna. They deputed Bhrigu to determine this answer.

Upon being entrusted with the task, Bhṛgu decided to test each of the Trimurti. He first visited Brahma at Satyaloka, and to test his patience, he refused to sing in his praise or prostrate before him. Brahma grew angry, but realised that his son was testing him and allowed him to pass. Bhṛgu left for Kailasha, the abode of Shiva. Upon seeing the sage, Shiva rose to his feet and moved forward with great joy to embrace the sage. Bhṛgu, however, refused the embrace, and tested him by calling the deity a maligner of social conventions and rituals. Shiva was infuriated and prepared to strike the sage with his trident, but was calmed by his consort, Parvati. The sage then travelled to the abode of Vishnu, Vaikuntha. Vishnu was resting his head on the lap of Lakshmi when the sage arrived. Bhṛgu kicked Vishnu on the chest to wake him up, enraged by the perceived insult. Vishnu woke up, greeted Bhṛgu, and starts massaging his feet, regarding his chest to have been sanctified due to its contact with the sage's foot. Overpowered with emotion, Bhṛgu went back to the sages and declared Vishnu to be the greatest among the Trimurti.

According to some traditions, Vishnu's consort Lakshmi grew angry at him because the chest was considered as Lakshmi's place (vakshasthala) and left Vaikuntha to be born on earth. She was found on a lotus flower, and was raised by Bhrigu and his wife Khyati, which is why another name of Lakshmi is Bhargavi, daughter of Bhṛgu. Since she was found on a lotus, she is also called Padmavati.

A variation of this is the legend behind Tirupati, in which a furious Lakshmi is born as Padmavati on earth and Vishnu assumes the form of Srinivasa and Venkateswara.
