Vikram Samvat is the historical Hindu calendar from the Indian subcontinent and the official calendar of modern-day India and Nepal. It uses lunar months and solar sidereal years.
Sage Vishvamitra is one of the most revered sages in Hinduism, known for his incredible spiritual power, dedication, and transformation from a king into a Brahmarishi (the highest rank of a sage). Originally a powerful king named Kaushika, he sought to attain the status of a sage through intense penance and meditation.
Vishvamitra is credited with the creation of powerful mantras, including the Gayatri Mantra, one of the most sacred and widely chanted prayers in Hinduism. He also played a significant role in the Ramayana, where he is depicted as the sage who guided and trained Lord Rama and Lakshmana in the use of divine weapons. Vishvamitra's story is one of self-transformation, showing the power of will and devotion in attaining spiritual heights.
