There will always be debate about the "true" meanings and techniques when dealing with the Tarot. There are fundamentalists who claim to have authority in this domain, and they can be quite intimidating. I urge you to decide what works for you, and honour that.
Personally, I place more value on experiential knowledge than on anything I read in a book. I know what works for me, and I urge you to actually *use* the Tarot, and rely on your own intuition and inner knowing to guide you. Of course, books and lectures are excellent sources of wisdom, and should never be disregarded. Particularly if you are just beginning, it is helpful to find a solid foundation on which to build your skills. Use these resources as your starting point, then dive deep into your own journey. Explore every avenue you find to learn what each card whispers to your spirit. Hold on to what resonates, and let go of anything else. You are a unique, one-of-a-kind being, so your relationship with the cards will be equally unique and one-of-a-kind.
Enjoy your journey, Love ❤ I wish you blessings along the way.
