The Saṃyutta Nikāya mentions an interview between an Elder of this name and the Sākyan Mahānāma. Mahānāma asks the Elder if the learner’s way of life is identical with that of the Tathāgata. Vaṅgīsa answers that it is not so; learners only abandon the five hindrances; arahants have completely destroyed them from the root. The interview took place in the Nigrodhārāma at Kapilavatthu.
The name Lomasavaṅgīsa is, probably, a wrong or variant reading for Lomasakaṅgiya. SN.v.327f.
