Whenever did the Indian Supreme Court declare all these religions as sect of Hinduism? Give a reference. Neither Supreme Court nor Constitution considers them same as Hinduism.
Please read Article 25 of Indian Constitution.
Jains, Sikhs part of broader Hindu religion, says SC
New Delhi, August 10 [2005]
In a significant ruling defining the status of communities like Sikhs and Jains within the Constitutional frame work, the Supreme Court has declined to treat them as separate minority communities from the broad Hindu religion, saying encouraging such tendencies would pose serious jolt to secularism and democracy in the country.
The so-called minority communities like Sikhs and Jains were not treated as national minorities at the time of framing of the Constitution. Sikhs and Jains, in fact, have throughout been treated as part of wider Hindu community, which has different sects, sub-sects, faiths, modes of worship and religious philosophies, a Bench of Chief Justice R.C. Lahoti, Mr Justice D.M. Dharmadhikari and Mr Justice P.K. Balasubramanyan said.

I thought in earlier times, there was no Pakistan. I don't see any mention of word Pakistan in any text or any documents made by various travelers, lets say 150 years ago.
Neither was there any India in the earliest times since over 9000 years ago. Why restrict it to only 150 years.
