Definition - What does Samantabhadra mean?
Samantabhadra is the name given to the pure essence of mind that has been achieved by all bodhisattvas.
On a practical level, samantabhadra refers to the idea that an enlightened person will show such great compassion that the entire universe benefits from it. Yoga and meditation are a means of reaching this sort of enlightenment.
Yogapedia explains Samantabhadra
This Sanskrit word is made up of two parts: samanta, which means "universally moving toward completeness," and bhadra, which means "great virtue."
In Buddhism, Samantabhadra is a bodhisattva (an enlightened, compassionate person) who makes up one part of the Shakyamuni trinity, alongside Gautama Buddha and Manjusri. He is also the patron of the "Lotus Sutra," an ancient text upon which Buddhism was partly established. For some Buddhist devotees, practicing yoga and deep meditation is a means of becoming the sort of bodhisattva that is represented by Samantabhadra.
