Ṣaṣṭha-prakaraṇam (Pratyāhāra) · Verse 3

नासाग्रे तु नभसि वा हृदये वा तथैव च । मूलाधारे तथा ब्रह्मरन्ध्रे वा धारयेत् सदा ॥

nāsāgre tu nabhasi vā hṛdaye vā tathaiva ca | mūlādhāre tathā brahmarandhre vā dhārayet sadā ||

This verse offers a precise methodology for anchoring the manas, or mind, through a series of strategic focal points. The instruction to hold the mind at the nasagra, the apex of the nose, in conjunction with nābhasi (space) and hridaya (the heart) establishes a foundational technique for calming the restless manas. Crucially, the verse extends this practice to the muladhara, the root chakra located at the base of the spine, and the brahmarandhra, the subtle opening at the crown of the head – places traditionally associated with profound spiritual insight. The constant retention of awareness at these points, particularly in ākāśa (ether), is presented as a means to quiet the flow of prāṇa and facilitate a stable samādhi. The emphasis on always holding the mind in these locations suggests a disciplined, sustained effort to cultivate a fixed point of awareness, a core element in both Rāja Yoga and the later systematic approach of Patañjali’s Yoga Sūtras.
