Hey guys,
Today I received a book on surya namaskara by Swami Satyananda Saraswati. I get the impression from a few parts of the book that one should learn the exercise from a teacher, otherwise it may be potentially detrimental to your health. I also saw a video on YouTube by Swami Ramdev for surya namaskara and in the description it is mentioned that an experienced teacher is necessary to learn.
Unfortunately there are few places for me to specifically learn surya namaskara here in the UK. Is it really necessary to learn from a teacher something that you can copy from innumerable books and videos? Does anyone have any suggestions?
