[paragraph continues] All the Ḍevas are in the heart; in the heart are all the prāṇas: in the heart are prāṇa, jyoṭis and that three-plied holy thread. In the heart in Chaiṭanya, it (prāṇa) is.  1 Put on the yajñopavīṭa (holy thread), the supreme, the holy, which came into existence along with the Prajāpaṭi, which gives long life and which is very excellent; let this give you strength and ṭejas. The wise man having shaved his head completely, should throw away the external thread. He should wear, as the holy thread, the supreme and indestructible Brahman. It is called sūṭra, because sūchanāṭ (indicating) (that the Āṭmā is in the heart). Sūṭra means the supreme abode. He who knows that sūṭra is a vipra (brāhmaṇa), he has crossed the ocean of the Veḍas. On that sūṭra (thread), everything is strung, like the beads on the thread. The yogin, well versed in yoga and having a clear perception of Truth, should wear the thread. Practising the noble yoga, the wise man should abandon the external thread. He who wears the sūṭra as Brahman, he is an intelligent being. By wearing the sūṭra, he is not polluted. They whose sūṭra is within, whose yajñopavīṭa is jñāna—they only know the sūṭra, and, they only wear the yajñopavīṭa in this world. Those whose tuft of hair is jñāna, who are firmly grounded in jñāna and whose yajñopavīṭa is jñāna, consider jñāna only as supreme. Jñāna is holy and excellent. He whose śikhā (tuft of hair) is jñāna like the śikhi (flame of agni)—he, the wise one, only wears a true śikhā; others wear a mere tuft of hair. Those brāhmaṇas and others who perform the ceremonies prescribed in the Veḍas—they wear this thread only as a symbol of their ceremonies. Those who know the Veḍas say that he only is a true brāhmaṇa who wears the śikhā of jñāna and whose yajñopavīṭa is the same (jñāna). This yajñopavīṭa (Yajña means Vishṇu or sacrifice and Upavīṭa is that which surrounds; hence that which surrounds Vishṇu) is supreme and is the supreme refuge. He who wears that really knows—he only wears the sūṭra, he is Yajña (Vishṇu) and he only knows Yajña (Vishṇu). One God hidden in all things, pervades all things and is the Inner Life of all things. He awards the fruits
