The verse is built on the repeated refrain “கணம் கணம்” (“moment by moment”), emphasizing kṣaṇikatva—instantaneous arising and perishing. The list mixes:

1) Yogic-psychological factors: “புலன்பொறிகள்” (sense-organs and their faculties), “அனுபவங்கள்” (experienced objects/feelings), “மனநினைவு” (mental recollection/rumination), and “மதியிழைவு” (decline of buddhi/clarity). This resembles a Siddhar’s diagnosis of the vṛttis (movements of mind) that continuously reconstitute a world.

2) Medical/physiological factors: “குருதி” (blood) indicates the body’s ceaseless circulation and also, in Siddha medicine, one of the primary bodily constituents/humors. By placing blood-flow alongside thought-flow, the verse collapses the usual divide between “mind” and “body”: both are streams of momentary events.

3) Breath/prāṇa as a central pivot: “வாசி” commonly denotes breath, subtle respiration, or prāṇic movement in Siddha-yoga; “விமல்” (stainless/pure) can indicate a purified breath-current (through vāsi/prāṇāyāma) or an epithet signaling an inner purity. The verse does not clearly celebrate mastery; rather it notes that even breath is a moment-by-moment phenomenon—yet it is also the traditional doorway by which citta may become steady.

The closing line—“In the citta that does not know the moment, they roam as dreams”—makes the epistemic point: ignorance here is not mere lack of information but lack of direct, present awareness (moment-recognition). Without that, the rapid succession of psycho-physical events is misread as continuity, and one lives inside constructions like a dream. The implied Siddha instruction is to cultivate moment-to-moment knowing (often via breath-awareness/discipline) so that the ‘dream-play’ of senses, memories, and bodily impulses is seen through rather than inhabited.
