ब्रह्मविष्णुसृष्टिकथनं नाम त्रयोदशोऽध्यायः
Description of the creation of Lord Brahma and Lord Vishnu – Chapter 13
Vayudeva said (to the sages)
एवं कल्पेषु कल्पेषु ब्रह्मविष्णुमहेश्वराः || 19 ||
परस्परेण जायंते परस्परहितैषिणः | 20
In this way, in kalpa after kalpa, Lord Brahma, Lord Vishnu and Lord Shiva are born by each other, who wish well of each other.
