KathaUpanishad

Deep within the nucleus of the heart, the Divine Light shines forth.
Through Bhagti, one meets the Lord.
The One Lord is pervading and permeating all; he Himself created the creation

Kaach kotam rachant toyam lepanam rakat charmanah ...:
This fragile body-fortress is made up of water, plastered with blood and wrapped
in skin. It has nine gates, but no shutters; it is supported by pillars of wind (the
channels of the breath). The ignorant person does not meditate On God;
because he thinks that this body is permanent (Guru Granth Sahib 1354).
Kaam krodh ar lobh moh ih indree ras laptaaye:
Man's senses are beguiled by sensual pleasures of lust, anger, greed and
emotional attachment (Guru Granth Sahib 403).
Naou dar thaake dhaavat rahaaye. Dasvai nij ghar vaasaa paaye ...:
Those who close off the nine gates, and restrain the wandering mind, come to
dwell in the Home of the Tenth Gate. There, the Unstruck Melody of the Shabad
vibrates day and night. Through the Guru's Teachings, the Shabad is heard. ||6||
(sggs 124).
Nagaree ekai naou daravaaje dhaavat baraj rahaaee ||
Trikuti chute daswaa dar khule taa manu kheewaa bhaaee.
Abhai pada poor taap tah naase kahi kabeer beechaaree ||3||:
There are nine gates or 9 openings (these are: two eyes, two ears, two nostrils,
one mouth, one genital, and one anus) to the one city of the body; restrain your
mind from escaping through them. When the knot of the three qualities of Maya
is untied, then the Tenth Gate opens up (God Realization), and the mind
becomes intoxicated, O brother ||3|| (Guru Granth Sahib 1123).
Geeta V. 13 also speaks of Nine gates.
Bhagavat Purana also describes the City of Nine Gates into which a King named
Puranjana lives. In Sanskrit, the word puran-jana means "one who enjoys in a
body."
These are gates to the material realm. The other two may be the gates to the
spirit world. Those who dare to enter through these two gates will be free
indeed.
The 11 gates may be the eleven orifices in the bodily system: the two
eyes, two nostrils, two ears, mouth, the two of evacuation, navel and the
crown of the head. But these are gates of only the gross body.
There are also eleven gates in the subtle body defined by the eleven
senses:
five jnanendriyas, five karmendriyas, and the mind.
