Inscription: April 1970: Translation of back of painting done by Dorje Yudron Yuthok:
'My humble salutations to the most loving, compassionate of all times - the past - present and the future.
The Great Protector, Maha Kala, the fierce God who is inseparable from my Lama (Guru).
To the Upper Tantric College, I present this thanka of the Great Protector, whose true spirit is ever present in the precious painting and is inseparable.
To you (Maha Kala) I pray that my good deeds be of service to all living beings from now until the time when all have achieved Buddhahood. May you the Great Protector always be near to us (never leave us) and help us to follow the path to righteousness. (from catalog card)
