Mokṣa-dharma Yoga-Upadeśa: Equanimity, Sense-Restraint, and Vision of the Ātman (आत्मदर्शन-योगोपदेशः)
दन्तांस्तालु च जिद्ठां च गलं॑ ग्रीवां तथैव च । हृदयं चिन्तयेच्चापि तथा हृदयबन्धनम्,दन्त, तालु, जिह्ला, गला, ग्रीवा, हृदय तथा हृदय-बन्धन (नाड़ीमार्ग)-को भी परमात्मरूपसे चिन्तन करे
dantāṁstālu ca jihvāṁ ca galaṁ grīvāṁ tathaiva ca | hṛdayaṁ cintayec cāpi tathā hṛdaya-bandhanam ||
One should contemplate, as forms of the Supreme Self, the teeth, the palate, the tongue, the throat, and the neck; and one should also contemplate the heart, as well as the “bond of the heart”—the inner channel (nāḍī) by which the vital currents are held and directed.
