SB Canto 1

SB 1.9.8, Purport:

Āṅgirasa: He is the son of Maharṣi Aṅgirā and is known as Bṛhaspati, the priest of the demigods. It is said that Droṇācārya was his partial incarnation. Śukrācārya was the spiritual master of the demons, and Bṛhaspati challenged him. His son is Kaca, and he delivered the fire weapon first to Bharadvāja Muni. He begot six sons (like the fire-god) by his wife Candramāsī, one of the reputed stars. He could travel in space, and therefore he could present himself even in the planets of Brahmaloka and Indraloka. He advised the King of heaven, Indra, about conquering the demons. Once he cursed Indra, who thus had to become a hog on the earth and was unwilling to return to heaven. Such is the power of the attraction of the illusory energy. Even a hog does not wish to part with its earthly possessions in exchange for a heavenly kingdom. He was the religious preceptor of the natives of different planets.

SB Canto 9

SB 9.18.22, Translation and Purport:

Because of falling in the well, I met you. Indeed, this has been arranged by providence. After I cursed Kaca, the son of the learned scholar Bṛhaspati, he cursed me by saying that I would not have a brāhmaṇa for a husband. Therefore, O mighty-armed one, there is no possibility of my becoming the wife of a brāhmaṇa.

Kaca, the son of the learned celestial priest Bṛhaspati, had been a student of Śukrācārya, from whom he had learned the art of reviving a man who has died untimely. This art, called mṛta-sañjīvanī, was especially used during wartime. When there was a war, soldiers would certainly die untimely, but if a soldier's body was intact, he could be brought to life again by this art of mṛta-sañjīvanī. This art was known to Śukrācārya and many others, and Kaca, the son of Bṛhaspati, became Śukrācārya's student to learn it. Devayānī desired to have Kaca as her husband, but Kaca, out of regard for Śukrācārya, looked upon the guru's daughter as a respectable superior and therefore refused to marry her. Devayānī angrily cursed Kaca by saying that although he had learned the art of mṛta-sañjīvanī from her father, it would be useless. When cursed in this way, Kaca retaliated by cursing Devayānī never to have a husband who was a brāhmaṇa. Because Devayānī liked Yayāti, who was a kṣatriya, she requested him to accept her as his bona fide wife. Although this would be pratiloma-vivāha, a marriage between the daughter of a high family and the son of a lower family, she explained that this arrangement was made by providence.
