What is meant by “buddhahood.” The Sanskrit word “buddha” has a range of meanings, such as “awakened,” “enlightened,” and “awakened to thusness.” Awakening to thusness can be attained relatively quicker in comparison to enlightenment, which requires a long time. In Tantric practice, buddhahood means complete enlightenment, and it takes a long time to attain. In short, different traditions define such terms as enlightenment and buddhahood in different ways.
