Bhagavad-gita As It Is

BG Chapters 1 - 6

The body consists of nine gates [two eyes, two nostrils, two ears, one mouth, the anus and the genitals]. The living entity in his conditioned stage identifies himself with the body.

BG 5.13, Purport: 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. The nine gates are mentioned as follows:

nava-dvāre pure dehī

haṁso lelāyate bahiḥ

vaśī sarvasya lokasya

sthāvarasya carasya ca

"The Supreme Personality of Godhead, who is living within the body of a living entity, is the controller of all living entities all over the universe. The body consists of nine gates [two eyes, two nostrils, two ears, one mouth, the anus and the genitals]. The living entity in his conditioned stage identifies himself with the body, but when he identifies himself with the Lord within himself, he becomes just as free as the Lord, even while in the body." (Śvetāśvatara Upaniṣad 3.18) Therefore, a Kṛṣṇa conscious person is free from both the outer and inner activities of the material body.
