Figurative
Bhagavad-gita As It Is
BG Chapters 1 - 6
When the embodied living being controls his nature and mentally renounces all actions, he resides happily in the city of nine gates (the material body), neither working nor causing work to be done.
The embodied soul lives in the city of nine gates. The activities of the body, or the figurative city of the body, are conducted automatically by its particular modes of nature. The soul, although subjecting himself to the conditions of the body, can be beyond those conditions, if he so desires. Owing only to forgetfulness of his superior nature, he identifies with the material body, and therefore suffers. By Kṛṣṇa consciousness, he can revive his real position and thus come out of his embodiment. Therefore, when one takes to Kṛṣṇa consciousness, one at once becomes completely aloof from bodily activities. In such a controlled life, in which his deliberations are changed, he lives happily within the city of nine gates.
