no i mean how does one go about doing that?
or the best way according to you
The best way is first to begin training by cultivation. Then the "training" with the energy.
Energy is meant to choose the way of least resistance and thus, it is very important to what purpose you direct that energy to, or to whom you want to direct that energy (in case you work with a human being).
You see, Ancient Roman system of magical workings relies strongly on the phases of the Moon. Romans used the moon as its symbolism is related to psychic powers, intuition, empowering oneself through the powers of water, the occult, and, if mastered, can lead to emotional balance and calm.
There are documented practices and their relation to moon phases, and the list goes:
New Moon: Best for setting new intentions, planting metaphorical seeds and beginning new projects. Basically, a time for renewals and new starts in life.
Waxing Crescent: Best for taking initial steps towards the goals set during the New Moon. Focus on growth and laying down roots.
First Quarter: Taking action and overcoming obstacles. It's a time to make decisions and put in effort toward achieving goals.
Waxing Gibbous: Best for refinement and fine-tuning. Focus on adjustments, perseverance, and aligning closer to your intentions.
Fool Moon: Celebrating achievements, embracing gratitude, and engaging in self-reflection. It's a time to honor yourself and others and give thanks for the blessings in your life.
That is applicable for most energy related workings.
Now, depending on other specifications of your working you may conserve and work with planetary energies when they are most powerful in the specific planetary hours. You should be able to find a list of planetary hours for your area.
And as for entities, although you don't conserve entities, you can still do a pseudo-conservation called energy tuning. You should have multiple sessions of communicating with the said entity you want to summon and try to tune to its energies. If it works, you successfully accommodated with that entity if not, don't be upset, it's the fact that your spiritual code has other tunes and plans for you.
Like, for example, with Angels, one may be tuned to Archangel Michael's energy more than Archangel Gabriel.
Same goes to the flip-side (the Demonic current) where some people prefer the energy of Lucifer instead of the more heavy energy of Satan.
I can say that it also goes to the polytheist currents of the Pantheons.
One may feel more attuned to the Nordic Gods than the Greek or Roman ones, for example.
