This meditational aspect of Manjushri may have one head and four arms, each holding an attribute: a bow, a sword, a blue lotus (utpala) topped with a book and an arrow. The above is seated on a double-lotus base with plump petals often seen on 13th and 14th century Tibetan sculptures, especially those made in Western Tibet.
The blue lotus has straight narrow petals with a sharp end to differentiate it from other lotuses.
The arrangement of the attributes is similar on this (Chinese) Yongle-style work (the arrow in one of his right hands is broken). His eyes are inlaid with silver and his lips with copper.
Manjushri Namasangiti may also have three heads and 6 hands, in which case he has the same attributes and two vajras, normally held in his middle hands over his heart. The above has lost his attributes except for the hilt of a sword. The way the ends of his celestial scarf rest rigidly at the front of the lotus base is typical of late (18th century onwards) Chinese-style works.
