Hi Petakubi! That was the perfect information to provide, the question, the cards, your interpretation and which deck you used
6 of cups + Hermit
The RWS 6 of Cups depicts an older child or dwarfed man sharing a cup with a young child. It typically means looking back on happier memories or taking care of your younger self. Inner Child work can be one message from such a card. It is also a card of collaboration.
The Hermit is a stark contrast. He is solitary, his way lit by his lantern with the Seal of Solomon within. The Hermit is the Old Wise Master within and seems like a pretty auspicious card for the kind of work that astral projection is part of.
Combined? My intuitive reading of these two cards is that you are trying to reach too far/too fast for astral projection. If that is the destination of a metaphorical journey? You still have life lessons to learn, esoteric/meditational techniques to master. Think of yourself like that young girl who has just been given a cup of Deep Wisdom. You need to sip at it slowly and look at everything going on in your life (both inner work and outer work).
Whatever text or system you are using to learn astral projection? Go backwards and make sure you are mastering the basic techniques or maybe try different approaches, other things like meditation, yoga, shadow work, guided visualization, qabalistic pathworking, take your pick and see if learning how to get your energies and True Will into alignment that way helps with astral projection.
Caveat: I am a theoretical magician. I'm terrible at meditation, yoga, astral travel and a lot of things because I am laaaazy and don't find the time/energy/motivation to do the consistent daily work it takes to get energies and True Will into alignment that way. It takes a lot of time/energy/motivation/focus.
