Did Jesus really died on the Cross or survived and lived his last days in India's Kashmir?

Yes He did die on the cross for real. He lost lots of blood from the whippings He got with the cat-o-nine tails. After that He was nailed to the cross for hours where he bled to death from the nails in His hands and feet. A final assurance of His death on the cross was when they drove a spear into His heart to make sure He was dead. If anything, the spear confirms His death on the cross.
