Many people pray or communicate with their Guardian Demon, or Father, and that is great. I've been doing that for quite a bit too, to great results. It's essential and I would argue it's just as essential as cleaning, AoP and other habits as a daily practice, a spiritual checkpoint during every day.
But communicating similarly with the other Gods can feed the soul in different ways, expose you to more diverse energies, and give you a wider perspective.
Today, I opened the Rituals site (the quickest way I use in order to access the sigils) to do my evening prayer to Father, but I had an intense intuitive desire to instead open Lady Astarte's page.
As per my usual practice, I focus on the sigil and meditate on the moment, trying to clear my mind, then breathe the sigil's energy into me similarly to foundation meditation, then speak my mind.
I felt a much different energy and attitude "watching" me, palpably different to Father.
The issues I discussed, emotions I vented, and plans I was making did indeed fit better with Astarte's dominions, and I feel like this intuition was good to follow.
I might dedicate specific days to try to become closer to specific Gods, and allow in their influence a bit more. This post is here to advise others to do the same.
The method I described above of prayer is also advisable when one wants to regularly stay within the Gods' "embrace", without the need to do God Rituals, as the more I advance, the more I understand that the God Rituals are not to be "spammed" (this is also emphasized highly by JGs and Clergy in the Temple.
