Sutra of the Ten Bhumis
Sutra of the Ten Bhumis (Skt. Daśabhūmika-sūtra, Tib. ས་བཅུ་པ་, Wyl. phags pa sa bcu pa'i mdo) - name given to the 31st chapter of the Avatamsaka Sutra, which describes in detail the ten bhumis. Vasubandhu wrote an important commentary to this sutra: the Dashabhumivyakhyana, which was only translated into Chinese, during the sixth century.
Just as one infers the presence of fire by seeing smoke,
Or the presence of water by seeing aquatic birds,
The presence of the intelligent bodhisattvas’ disposition
Can be understood from certain signs.
