हिमालयं समारभ्य यावत् इंदु सरेावरम् |
तं देवनिर्मितं देशं हिंदुस्थानं प्रचक्षते ||
Starting from Himalayas and extending upto Indu sarovaram (Indian Ocean) is the nation created by God which is known as 'Hindusthan'. Himalayan ranges including Hindukush parvat on Western side and the ranges extending upto North Myanmar ( Brahmadesh) on the Eastern side formed the Northern Boundary of ancient Hindusthan. This land extended upto the Indian Ocean on the Southern side. This is the sacred land where God took Birth from time to time and recreated and established the social structure.
