Caturthopadeśaḥ (Samādhi) · Verse 59
यदा सङ्कल्पजालं च वायुरल्पीभवेद्यदा | आत्मनि ब्रह्मणि लीनं समाधिरभिधीयते
yadā saṅkalpajālaṃ ca vāyuralpībhavedyadā | ātmani brahmaṇi līnaṃ samādhirabhidhīyate
When the network of intentions and air become minimal, dissolved into the Self in Brahman, it is called samādhi.
Saṅkalpajāla — the network of intentions, purposes, volitions.The term saṅkalpa denotes the volitional activity of the mind: wanting, planning, deciding, imagining futures.This web (jāla) traps consciousness in constant worries about what should be.
When this network and the vāyu (air/breath) become alpī (minimal, subtle), dissolution (līna) into ātman and brahman occurs.The text uses both terms, emphasizing that the individual Self and the Absolute are ultimately one.
The connection between saṅkalpa and vāyu is significant.Yogic texts affirm that mind and breath are linked: when one is agitated, so is the other.When mental intentions become still, the breath naturally becomes subtler.And vice versa: the practice of prāṇāyāma calms the torrent of saṅkalpas.This reciprocity is the basis of haṭha yoga as a path to samādhi.
