14. For meditation, owing to the absence of purpose.
As no other purpose can be assigned, the text must be supposed to represent Brahman as having joy for its head, and so on, for the purpose of meditation. In order to accomplish the meditation on Brahman which is enjoined in the text 'he who knows (i.e. meditates on) Brahman reaches the Highest,' the text represents the Brahman consisting of bliss as made up of joy, satisfaction, &c., and compares these to the head, the wings, and so on. The Self of bliss, which is the inmost of all the Selfs mentioned in the text, is by this means represented to the mind in a definite shape; just as in the preceding sections the Self of food, the Self of breath, and the rest had similarly been represented in definite shapes, consisting of head, wings, and so on. As thus the qualities of having joy for its head, &c. are merely secondary marks of the Self of bliss, they are not necessarily included in each meditation that involves the idea of that Self.
