The reference may be to a contemporary adherent of his school of yogis. The name does not occur in Guru Nanak's Sidh Gosti, but another of his hymns in Raga Ramkali is addressed to a yogi, there mentioned as Machhindra. The Guru says that true yoga meant not austerities but overcoming the Five Evils; that the true avadhuta, i.e. renouncer or recluse, is [not one who renounces the world but] one who remains absorbed in contemplation; and that such a one begs for [not alms but] devotion, rejoices in the invaluable gift of contentment, and fixes his mind on the True Name (GG, 877).
