Bollée, Willem B., 2010. Remarks on the cultural history of the ear in India. Pp. 141-167 in: Balbir, Nalini (ed.) 2010. Svasti: Essays in honour of Professor Hampa Nagarajaiah for his 75th birthday. Bangalore: K. S. Muddappa Smaraka Trust.
On p. 145 Bollée discusses the form of the ear, starting with “Karṇa ‘Longear’ (?)” and “Vikarṇa ‘With widely extended ears’” … “Long ears are a positive mark of Mahāvīra (…); such people, however, are to be excluded from the sacrifice to the dead.” …
Best wishes for a Happy New Year 2022,
