Here is what worked for me. Study tarot. Start doing readings.
While doing readings, be open to “weird thoughts”, and feelings.
I always had an inclination towards this. My sister and I used to practice “sending thoughts” back and forth. We creeped ourselves out more than a few times…still do.
But Tarot provides you with a set of archetypes to work with. It is a foundation to build upon.
Stay ‘open’, and keep studying. Let the rest happen. Try to force it, and nothing will come of it.
Buy one basic deck (an RW), and have fun.
...I have two books by an author named Sonya Choquette. One is titled "The Psychic Pathway" and the other is titled "True Balance".
The first deals with ways to connect with your inner self and thereby open your pyschic self. The second book deals with much the same, but specifically with balancing your chakras, both as a way to heal and to open yourself up.
I really enjoy these books. I've had the first for years and refer/rework through it many times. I've just recently bought True Balance, so I haven't worked through it completely yet. I like the author's writing style and how she is able to relate her personal stories as examples.
you could try asking your spirit guides for help in "hearing" them, and for clarity.
allow yourself some quiet/meditation time daily. learn to focus your mind, so to clear it from distractions. this doesn't mean that you cannot hear anything else, you will be aware of everything, but the distractions will be background noises and not take center stage.
above all, realize that developing these skills, is a lifelong journey, so go easy on yourself and have fun!
