I pretty much agree with the others, it is okay to incorporate bits of different things into your path as long a you do not claim to represent that path. I have picked up much for Taoism but I am not a Taoist, I incorporate bits of hoodoo, witchcraft, Native American beliefs, Wicca, Siberian shamanism, Norse beliefs, Celtic beliefs, Classical mythology, Voodoo, Chaos magic, Hermetic philosophy and more, but it is my own path. I do not claim to represent any of those paths but it is okay to say you were influenced by a path. It is much in the same way that an original artist who is creative can use influences from many artists. If a person wishes to follow a specific path, they must study that path with devotion from a traditional teacher and some are culturally specific where you must be born into the culture. I used to tell my coven that many answers are like a grey scale, a few things are pure black or pure white but the bulk of it falls into shades of grey. This particular question falls into situational ethics, where you look at it on a case by case basis. Using a technique or type of energy, is not the same as borrowing a culture, you have to look at what exactly you are trying to do in each case.
