Srimad Bhagavatam Canto 10, Chapter 63, Text 37

SB 10.63.37

tavavataro ’yam akuntha-dhaman
 dharmasya guptyai jagato hitaya
vayam ca sarve bhavatanubhavita
 vibhavayamo bhuvanani sapta
Your current descent into the material realm, O Lord of unrestricted power, is meant for upholding the principles of justice and benefiting the entire universe. We demigods, each depending on Your grace and authority, develop the seven planetary systems.
As Lord Siva glorifies Lord Krsna doubt may arise, since, apparently, Lord Krsna is standing before Lord Siva as a historical personality with a humanlike body. However, it is out of the Lord’s causeless mercy that He appears to us in a form visible to our mundane eyes. If we want to understand the Absolute Truth, Sri Krsna, we must hear from recognized authorities in Krsna consciousness, such as Lord Krsna Himself in the Bhagavad-gita, or from Lord Siva, a recognized Vaisnava authority, who here glorifies the Supreme Personality of Godhead.
