I'll just copy paste some good answers from Johnson Akemi on another thread:
"To open your astral sight and hearing and be able to telepathically communicate with a Demon, you need to meditate on your 6th chakra, 3rd eye, clairaudience points, clairvoyance points, and pineal lobe."
You should read the thread as she also gives some warnings and advice on dealing with spiritual beings and how to protect yourself from attacks:

Here are informations and links to good ways of dealing with negative energy from others:
"On a lesser note, those who deliberately try to do you harm in your life, simply direct their own energy right back to them, using the grey tones. Sit back and watch them suffer and revel in it."

Some advice when working with your Chakras is to keep a balance:
"Each chakra has a male and female pair and both work together. There must be balance in both the higher and lower chakras."
