Definition - What does Brahmarishi Vishwamitra mean?
Brahmarishi Vishwamitra was one of the most revered of India's ancient Hindu sages. Brahmarishi is a title given to the highest level of rishis, or sages and translates as “divine sage.” The name, Vishwamitra, also comes from the ancient Sanskrit language, meaning “friend of the world.” He was known for his perseverance and piety.
Believed to have written much of the third book of the sacred text, the "Rig Veda," Brahmarishi Vishwamitra is credited with authorship of one of the best-known Sanskrit mantras, the Gayatri mantra, which is also found in the "Rig Veda."
Yogapedia explains Brahmarishi Vishwamitra
According to Hindu mythology, Vishwamitra was once a king named Kaushika, who after witnessing the power of the sage, Vashishta, renounced his throne and practiced penance through yoga and austerity measures known as the tapas. Eventually, Lord Brahma rewarded his devotion with the name change and the title of brahmarishi.
Vishwamitrasana, or Sage Vishwamitra's pose, is an advanced arm balance posture that provides an intense side stretch. It represents the challenges Brahmarishi Vishwamitra faced on his spiritual journey. From triangle pose, the forward leg is lifted and the arm that is extended to the sky reaches behind the head to grasp the uplifted foot. The pose is also sometimes called flying warrior.
