The national emblem of India is an adaptation of the Lion Capital of Ashoka at Sarnath. It was adopted on 26th January 1950, the day India became a republic. The emblem features four lions standing back to back on a circular abacus, which is placed on a lotus in full bloom. The abacus rests on a bell-shaped pedestal, which is intricately carved with four wheels and four animals, which are a lion, an elephant, a horse, and a bull.

The Lion Capital of Ashoka at Sarnath is a pillar that was built by Emperor Ashoka in the 3rd century BCE. It is made of polished sandstone and features four Asiatic lions standing back to back. These lions are believed to represent power, courage, pride, and confidence. The lions are mounted on an inverted bell-shaped lotus, which is a symbol of the Buddhist Dharma.

The original Lion Capital of Ashoka is now housed in the Sarnath Museum in Varanasi, Uttar Pradesh. However, replicas of the Lion Capital can be found all over India, including on the Indian currency, government documents, and official seals.

In conclusion, the national emblem of India has been taken from the Lion Capital of Ashoka at Sarnath, which is a pillar built by Emperor Ashoka in the 3rd century BCE. The emblem features four lions standing back to back on a circular abacus, which is placed on a lotus in full bloom. The emblem is a symbol of India's rich cultural heritage and its commitment to peace, unity, and prosperity.
