Mantra 6

याज्ञवल्क्येति होवाच यदिदमन्तरिक्षमनारम्बणमिव केनाक्रमेण यजमानः स्वर्गं लोकमाक्रमत इति ।ब्रह्मणर्त्विजा मनसा चन्द्रेण ।मनो वै यज्ञस्य ब्रह्मा ।तद्यदिदं मनः सोऽसौ चन्द्रः स ब्रह्मा स मुक्तिः सातिमुक्तिरित्यतिमोक्षा ।अथ संपदः ॥३,१.६ ॥

In plain words

"Yājñavalkya," he said, "since this middle region is as it were without a support, by what ascent does the sacrificer mount to the heavenly world?" "By the Brahman priest, by the mind, by the moon. For the mind is the Brahman priest of the sacrifice; and what the mind is, that is the moon, and that is the Brahman priest. That is release, that is complete release." So much for the complete releases. Now the correspondences.
