ஒரு வேளை யோகி யிருவேளை போகி
ஒரு மூன்று வேளை யவன் ரோகி
உருவான யோனி யுடனான போகம்
உடல் கூடவென்றும் தளராது
oru vēlai yōgi yiruvēlai pōgi
oru mūnru vēlai yavan rōgi
uruvāna yōni yuṭanāna pōgam
uṭal kūḍavenrum thaḷarāthu
Eating once (a day) — one is a yogi; eating twice — one is a bhogi (an enjoyer); eating three times — that man is a rogi (a diseased one). Pleasure/union with the properly formed yoni: even when the body comes together (in union), it will never become slack/weak.
Measured intake is the first austerity: reducing meals disciplines desire and stabilizes health. Likewise, sensual pleasure is not rejected outright; when “union with the yoni” is undertaken in a right/ripe manner (proper partner, proper method, proper inner yogic condition), bodily vitality is not depleted and weakness does not follow.
The opening triad is a Siddhar-style diagnostic aphorism linking frequency of eating with states of consciousness and health: once-a-day eating implies restraint (mitāhāra) and yogic orientation; twice implies ordinary enjoyment; thrice indicates indulgence that tends toward disorder (roga). In Siddha medicine, overeating is a primary cause for derangement of vātham–pitham–kapham, heaviness, dullness, and loss of prāṇa clarity—hence the blunt equation of “three meals” with disease.
The second half complicates any simple ascetic reading. “Yoni” can be literal (female generative organ/womb) and also symbolic (source, matrix, vessel, seat of Śakti). “Bhogam” (enjoyment/union) is placed alongside the earlier “bhogi,” implying that pleasure becomes harmful or harmless depending on measure and correctness. The claim that the body does not “thalarāthu” (slacken, weaken, lose firmness) suggests the Siddhar concern with conserving ojas/viriyam (vital essence). In a yogic-tantric register, “union with the yoni” may also point to an inner conjunction: Śiva–Śakti, iḍā–piṅgalā resolving into suṣumṇā, or the rise of kuṇḍalinī from the yoni-like base center—an alchemy of energies in which ‘enjoyment’ is transmuted rather than spent. Thus the verse teaches discipline without blanket negation: moderation in food and a “right” form of union lead to steadiness rather than depletion.
