You have a solid meditation program. Have you been doing these meditations consistently without long breaks in between, or even intermittent breaks?
For example, one can do the full chakra meditation for 15 years, but if one only does once every 2 or 3 days, advancement will be inconsistent and almost no progress will be made.
Same would be if someone does the full chakra meditation everyday for 3 months, and then takes a 2 week break and does nothing, then slowly picks it up again. Almost all progress would have fallen by the wayside and one would get stuck not really progressing.
Same applies to all other meditations really.
Then about feeling energy, you didn't answer my questions. I asked them, because to communicate astrally and also to advance spiritually it is important to feel energy strongly.
If you do not feel much of anything when meditating, it is hard to communicate as it means one is not in tune with the energies of their soul.
The method you use to communicate is fine.
You can try this:
Go to the JoS demons and Gods of Hell section and tell openly of your concern that you haven't felt any communication yet and that you desire to have a positive relationship with the Gods and Goddesses of Hell, that you wish to get to know them, to communicate with them and be able to see them, to have positive experiences with then in order to help your growth as an SS.
Talk about that openly with the intent to have the Gods and Goddesses hear this.
Then politely ask Satan (even if you cannot hear or feel anything yet), to help you connect with one of the Gods or Goddesses and establish communications with them.
While in a light trance go over the list of named Gods and Goddesses, tune into the names of the Gods and Goddesses individually, and see if you get a strong reaction in your mind from one.
The moment you feel a strong reaction, like a desire out of nowhere to know more about this particular God or Goddess, or a strong mental pull towards their name, see if they have a sigil.
If they have a Sigil, open it, and look at it for a bit until you can visualize it in your mind (You can also draw it down on a piece of paper). Then visualize the sigil in your mind while vibrating the name of this God or Goddess.
In your mind, politely ask if they can communicate to you, give you a sign that they have heard you, or help you establish a channel of communication with them.
You should receive a sign from this, or a feeling at least.
If not then repeat this daily after empowering of your astral senses, and really tell yourself that you succeed in receiving a sign from the Gods, that you succeed in establishing communications with them.
If the God or Goddess you feel a pull towards doesn't have a sigil, then focus strongly on their name and vibrate it with the intent to connect to them and get to know them.
If you do not feel any mental pull towards any of the Gods, then ask Satan himself and communicate to Satan himself.
Explain to him how you struggle to feel anything or connect in any way, and communicate with him. Just talk about your concerns regarding this while in a high energy state after meditation and express strongly your desire to know him and speak with him.
Do this for about 15 minutes at a time, and just try it again the next day if it didn't work.
It helps to be in trance beforehand and to have a clear mind devoid of distractions.
Hail Satan!
