One of a series of portraits of this master framed by lotuses that support a manuscript and the hilt of a sword. His left hand is in the meditation gesture and may have held an attribute, the right hand does the teaching gesture. An inscription on the rim of the base gives us his name and that of the patron, Sonam Pelzang.
Seated on a single lotus base, Lowo Khenchen Sonam Lhundrup holds a flaming jewel in his left hand.
Seated on a double lotus base, same iconography (the forefinger on the right hand appears to be broken), the facial features less life-like.
He is wearing the Sakya bonnet and the border on his vest and robe is incised with a large floral motif. The eyes are inlaid with silver and the lips with copper.
