In Tibetan sculpture, lamas are sometimes depicted with thick hair combed backwards.
This lama is adorned with jewellery, he had a stone-inlaid urna and wears a gown with a richly incised hem. These features, along with the shape of the double-lotus base, help date the piece. We will note the very ornate way in which the tail end of his garment is arranged over the base.
This lama, with part of his hair tied up, recalls sculptures of Jigme Lingpa, although the latter is usually shown much thinner (see below).
This type of hairstyle is a status symbol in many cultures across the world. However, in Tibetan buddhism it has an esoteric/religious meaning and is not meant to indicate any form of superiority, obviously.
