Answer by Tejasvita Apte:
This is going to be new for many –
Before I come to my answer, picture the following –
1) Adi Shankara, born in present day Kerala, a scholar of Tamizh and Sanskrit is received with reverence all over India.
In Dwarka (present day Gujrat) the king attends his discourse along with the nobles. When he visits the royal court, the king washes his feet.
In Nepal, he is received as a royal guest. In Kanchi, Tamil Nadu he consecrates a yantra. He engages intellectuals in debates held in front of large numbers in Kashi present day Uttar Pradesh.
Nobody questions his genius. He is revered and even today he is considered the biggest influence in reviving Hinduism.
He spoke Tamizh.
Picture this too –
2) Guru Granth Sahib is compiled.
It contains not just the works of Gurus themselves but also the works of Jaidev, Farid, Nam Dev, Trilochan, Paramanand, Beni, Dhanna, Sain, Kabir, Mira, Surdas, along with Sufi seers, each of them belonging to a different part of the India.
3) Now picture the deities in Hinduism –
Animals worshiped by tribes are never denigrated or suppressed as 'Paganism'. Instead they are given a place of honor.
4) Now look at the practices and rituals –
Only Namboodries from Kerala are priests of the Badrinath Temple in Himalayas.
The priests of Pashupatinath Temple are (were) from Karnataka.
The priests in Rameshwaram are from Maharashtra.
The Kamakshi Temple in Kachi is linked to the Kamakhya temple in Guwahati.
Every Diwali the sari of the deity Amba in Kolhapur (Maharashtra) comes from Tirupati in Andhra.
In Kedarnath, present day Uttarakhand, you will find all the plaques composed and written by Shakaracharya in Tamizh.
Though nobody understands it there, it is respected and honoured.
The Sankalpa mantra before every puja has references of every major river throughout India.
The bath in the Ganges isn't complete unless one takes Darshan (also visits) of the Setu in Rameshwaram, Tamil Nadu.
If this is not a proof of unity and integrity, I don't know what is!
Now, coming directly to the answer –
Firstly, Hinduism is a religion and Sanskrit and Tamizh are languages.
Once upon a time, Hinduism spread way beyond what is India today (to Cambodia, Malaysia, Indonesia, etc).
Tamizh and Sanskrit go together as much as any two languages belonging to different families go together.
As far as Hinduism is concerned, nothing really is enforceable. There is no one language, God, ritual, absence of it, anything really that is mandatory.
It is moreover like an umbrella of umpteen beliefs.
Choose yours. And while you are at it, feel free to use Chinese, Japanese, Hebrew or Farsi. God is cool with that.
Next time, before you look at the differences, look at the similarities. India is indeed unique!
