Tṛtīyopadeśaḥ (Mudrā) · Verse 41
खेचरीमुद्रया योगी ब्रह्मरन्ध्रं तु पश्यति | ततो योगी ब्रह्मण्वेति प्रजायते न संशयः ||
khecarīmudrayā yogī brahmarandhraṃ tu paśyati | tato yogī brahmaṇveti prajāyate na saṃśayaḥ ||
Final verse of Khecarī mudrā, identical to 3-37. The complete description occupies 21 verses, more than any other technique in the text.
The vision of the brahmarandhra and the knowledge of Brahman are the culminating result. Everything previous — health, longevity, powers — is preparation for this.
For the modern practitioner, “gentle” Khecarī (touching the palate where the tongue naturally reaches) is still an extremely valuable practice. Constancy is more important than extreme intensity.
