Chapter-8
कूटस्थदीपोनाम – अष्टमः परिच्छेदः
The Flame of the Essential Self.
“The Body and the Kutastha“
खादित्यदीपिते कुड्ये दर्पणादित्यदीप्तिवत् । कूटस्थभासितो देहो धीस्थजीवेन भास्यते ॥1॥
The wall becomes visible in the light of sunrays reflected from the mirror. Much in the same way the body becomes perceptible in the light of Kutastha reflected in the intellect.
अनेकदर्पणादित्यदीप्तीनां बहुसन्धिषु । इतरा व्यज्यते तासामभावेऽपि प्रकाशते ॥2॥
Coming from several mirrors, there could be many reflections on the wall which is also illumined directly by the Sun and the spaces between the reflections are lit up by the sunrays only. And even if there is no reflection lighting up the wall, it would still be visible in the direct sunlight.
