Saraswati the goddess of knowledge, who is praised by the wise, who is the wife of the creator, may she reside on the tip of my tongue.
Dancing Saraswati Statue, the Hindu Goddess of wisdom
Saraswati, goddess of knowledge and the arts, embodies the wisdom of Devi. She is the river of consciousness that enlivens creation; she is the dawn-goddess whose rays dispel the darkness of ignorance. Without her there is only chaos and confusion. To realize her one must go beyond the pleasures of the senses and rejoice in the serenity of the spirit.
