'You eat food and see your desire, and whoever thus meditates on that Vaisvânara Self, eats food and sees his desire, and has Vedic glory in his house. That, however, is but the trunk of the Self, and your trunk would have perished, if you had not come to me.'
In plain words: The king says space-worship brings food, wishes and honor. But space is only the body, or trunk, of the universal Self. Without the fuller teaching Jana's body might have perished.
