Buddha Shakyamuni is the founder of Buddhism in this world.
In general, “Buddha” means “Awakened One” — someone who has awakened from the sleep of ignorance and sees things as they really are.
A Buddha is a person who is completely free from all faults and mental obstructions. Every living being has the potential to become a Buddha.
See the book Introduction to Buddhism for Buddha Shakyamuni’s life story and the sadhana Prayers for Meditation and the CD Songs of Good Fortune for the Guru yoga of Buddha Shakyamuni.
