Harvard Institute for Economic Research developed the following map, showing the Ethnic Diversity in green areas with a high rate of diversity. India is not an Ethnically diverse but culturally diverse Nation.
Indian multiculturism, even though so, has a common source of origin, none other than ancient Vedic Civilisation. Bharatiya Sanskriti enjoys a unique homogenous pattern, which is essentially a sense of Cosmic Unity [Brahman] of all living and non-living beings within ‘private’, ‘public’, and universally levels.
This sense touches all spheres of life, whether it is food habit, music-dance, architecture or Religious[Pantha] groups. Indian use ‘ Adhyatma’ to indicate the inner meditative reality. Adhyatma of the all religious groups such as Saiva, Sakta and Vaishnav are the same in one level. On the other level Marathi, Gujarati, Bengali and Manipuri etc are different in socio-cultural outlook, but even then they have a homogeneous pattern. North Indian Rangoli is uniquely similar with Keralian Rongoli. A Tamil family follows the same marriage ritual as a family live in Ludhiana Area. Marathi Avhang kirtan is obviously similar with Manipuri Vaishnava Kirtan.
Brahman- Universal Level
Pra-Brahman- Unseen Universe
Ethnicity- Samaj. Such as the Ethnicity of Hidimba was different from her husband Bhima in Mahabharata. In the same way, Rama was a Nara and Sugriv was a Ba-Nara. Ba Sanskrit root means short stature. compare Ba-man, Ba-suki. Bali means a man with shorter hair and Sugriv means a man with muscular hands. the ethnicity of Rama- Hanumana and Bhima were same. The culture of Hanuman and Rama were different. The Culture of Hanuman was similar with Bali and Sugriva.
Class-Varna-Working class Sudra Varna
Patriarch- Gotra- Such as Kashyap Gotra
Family- Vamsha- Such as Yadu Vamsha
Clan- Kula- Such as Rakshas Kula Ravan was a Brahmin Varna
Jati-Origin-Such as Manushya/Human Jati
Arya – A gentleman
Racial Factor- unknown in the Indian context
Now Ethnicity may have a connection with race, but they’re not the same thing. A race is ‘biology’ in the western sense. A particular DNA pattern with the infinite inner combination in connection with Exome. DNA patterns of pan Indians are the same, whether somebody is from the South or North East.
Thus Indians are a Single group and presently one Nation [Political nationality is a new concept] wit multicultural trait.
The Dharma of Rama-Ravana-and Sugriva is same- ‘Dharma dharyate jagata’ old Vedic maxim, that the rule of Dharma compelling and inescapable either for Rama or for Ravana. dharma is not Statute or Common Law or observation of a Judge. Dharma is not again a Constitution. Dharma is not Ohi/command of Yahe or Allah. Dharma is not concurrence in a council. As per Gopath Brahman Dharma is secret epistemology. Due to Dharma the dynamic society exist. Dharma defines everything, but anything is incompetent to define Dharma. Dharma consumes Manu`s law, Dharma consumes the consciousness of yoga, Dharma consumes before and afterlife circumstances. Dharma consumes Avatars, Dharma consumes scriptures — Dharma consumes psychological behaviours of a particular human being. Dharma is fire/ Agni in Rig Veda, Dharma is Indra / sensual consciousness, dharma is Bayu/ Oxizeneted air, Dharma is Vishnu/ Substance, Dharma is Rudra/state of nonexistence, Dharma is Yama/molecular frequency, dharma is Ishan/ Morality, dharma is Ashinas/ Duality, Dharma is Basu/Container, Dharma is Shiva/Contained.
Indian nationhood[ historical or political] recognise Dharma as common root of all Bhartiya People. Bha-Rata, the practitioner of Dharma.
