Mr Jesse Schell, born and raised in the West, values the importance of scientific enquiry and freedom of thought. Trained and educated in the sciences, he holds two degrees in nursing. He is also trained as English as a Second Language teacher with a CELTA degree from Cambridge University. This background and experience in science and language has allowed him to contribute to this work of Dr Chahal. A religious/spiritual seeker all of his life, Mr Schell has studied a number of religions and spiritual practices over the years. After much study, questioning, and serious thought it was clear that sound reasoning overcomes blind faith and so he always found himself abandoning each religion. He now describes himself as a secular humanist with Deist leanings, a free-thinker while being 'iconoclastic for good reasons'.
He finds that the current state of Sikhism is deplorable, demonstrating all the reasons why religion is evil. None-the-less, he feels a strong attraction to the original teachings of Guru Nanak (not current Sikhism) and it is for this reason that he has given generously of his time and abilities to further Dr Chahal's most important and greatly needed scholarly work. Currently, he lives in rural New Zealand, practicing self-sufficiency with his husband and their five dogs.DOWNLOAD THE BOOK HERE
