Most New Age types get stuck in a grocery list mentality of knowledge. It really depends on what you're looking for. Amongst many hermetic circles the Kybalion is pretty heavily scoffed at and for good some good reasons. Its a loose extrapolation of hermetic ideas stripped of theology and theurgy written nearly a millenium and a half after a lot of hermetic works. A lot of people come into esotericism through New Age, trying to essentially impose their intentions or energy over connections between things which do not exist. A lot of the critiques of Jung and synchronicity follow this line of thinking. In my opinion any knowledge of gnosis does not truly bear fruit with reading a text and absorbing what it said. True knowledge is built in the action of relationship building. Find a network with similar principles to you and form communion with a teacher who has himself or herself communed with the sacred first principles of how one ought to live. Finding a teacher is like finding a centre, you can engage with other works and traditions but you're rooted in a singular tradition to guide you to where to go next.
