A basic technique to get more attuned with astrological energies is to meditate on each symbol. Planetary symbols, Zodiac symbols, element, even aspect symbols. Surrender yourself to the visualisation and explore the energies to understand them.
:arrow: You can start by printing the symbol and putting it in front of yourself. Printing it in the specific colour can help.
:arrow: Before starting to focus on the symbol, you can also ask Father Satan, your GD or even a specific God/dess that is expert in astrology to help you and guide your session. This is optional but always very helpful and the Gods like teaching us, so there is no reason why you shouldn't get in touch with them for help.
:arrow: When you can have the symbol completely memorise, you can go into a deep trance and visualise it in your mind. Breathe in its energies and connect to it. (Avoid doing this with outer planets like Uranus, Neptune and Pluto. Saturn is also controversial.) See, feel, hear, smell, taste... involve all senses, inner and outer.
:arrow: Clean yourself thoroughly after all is said and done.
A step further is to put to meditate on multiple symbols at once and see how the energies interact in the various aspects and placements.
A step even further is to meditate on a chart.
Those more advanced can use the merging consciousness technique to have the deepest exploration experience.
After you are familiar with each astrological item, it is important to read lots of charts as often as possible, even on a daily basis.
This is the spiritual way to do this. Of course, there can be delusion and misunderstandings coming from prejudice and bias that can be unconscious but as one advances this will gradually clear up. The information you gain from this method can and should always be tested and applied to actual charts. And, since one is studying/learning, they need to try to apply this multiple times over as that's the only way you can verify it and reinforce your knowledge.
This method can be as inaccurate as reading non-SS books, more inaccurate or more precise. It all really depends on where you are at, and how seriously you take your studies.
I am mentioning this method because I never heard anyone suggesting anything similar. It can be used on its own or paired with reading books. Keep in mind, however, that your readings may influence the method, whether you read accurate stuff or not, as it's normal.
Another way of reinforcing this practice, is to chant specific runes before, such as Dagaz, Lagur... Runes that bring knowledge and awareness in general. You can also perform this after working on your astral senses or your head chakra (crown, temples, sixth, pineal gland, minor points of clairvoyance and clairaudience).
They say it takes 10 thousand hours to master anything. This is the equivalent of working an average job (40 hours a week) for 5 years, to make a rough example. Best of luck on your studies!
