In Tibetan Buddhism, the sutra known as the Prajnaparamita Perfection of Wisdom was deified as an aspect of White Tara. This Tara is also related to the Indian Sarasvati who is the deity of letters, music and the other intellectual pursuits.
Similar to the devotion given Buddha Amitabha is the movement which originated in the teachings of Nichiren who lived in 13th century Japan. He promoted the idea that the text known as the Lotus Sutra was itself a sort of deity having soteriological saviour-like powers. This sect is quite popular today in the West.
Tina Turner, the successful singer, stated in her autobiography that she owes her success in overcoming a difficult series of life-situations to her daily repetition of the Lotus Sutra mantra: Om namo myoho rengeh kyo which combines Sanskrit and Japanese.
Buddhist teachers of all schools stress that all such deities are to be thought of as embodiments of wisdom and compassion, not separate from the practitioner or meditator, and ultimately empty of any inherent qualities.
