What teachings? The teachings of Hinduism are not at all unique to Hinduism. They are found in Neo-Platonism; Gnosticism; Sufism; Taoism, Shamanism. Therefore it becomes clear that the teaching of Hinduism are NOT a religion-specific belief, but teach something universal. This is the reason why Swami Vivekananda has taught these teachings to the West by paying less emphasis on Hinduism - because the teachings matter more than Hinduism.
You are trying to copyright something which is public knowledge. Not possible Hinduism simply presents the best and most accurate articulation of the truths about spirituality out of all spiritual traditions on this planet, but it is articulating the same common truths found all cross all spiritual traditions in the world. Therefore these teachings are universal. No matter how much you try, you will never be able to copyright them as Hindu only.
Besides, like I said before we’ve learned all we can from the Hindu tradition of spirituality. The ancient Hindu sages did a fantastic job in exploring spiritual truths, but their methodology was not as sophisticated as we have today e.g. they did not have MRI scanners for one. We have far better methods and tools today to explore these truths better. Hence, the Hindu tradition is now obsolete. 21st century research on spirituality is far more developed than anything you will ever find in any of the Vedic texts.
