His personality: Really nice, He wants whats best for everyone basically. I find He is easy for me to talk to and He can give good insight on issues. If I have questions its best to just ask Him. He can be blunt, if something isn’t going to work He will tell you that it won’t work, etc. But He can be supportive to a point. Wise older man, to put simply, is my all around impression of Ra.
Activities: For simple activities, (from personal experience) going outside on a sunny day and talking to Him is something He seems to enjoy. The last time I did this I walked to my favorite spot in the park and I just talked to Him the majority of the time. Also, He is okay with devotional cleaning, as He likes clean spaces. For more elaborate activities, heka, learning about heka and doing it are options. I do get the feeling that dressing up and being fancy in His honor are good options too (based on His epithet Lord of Adornment, He is a king after all). Making art, any art really (since art is creating) is also a good option. Learning creation mythology of Egypt has been helpful for my personal relationship with Ra so far. Learning about Egypt and the “old ways” of the kemetic religion is good too (ive seen somewhere about other Ra devotees saying He can be kind of “stuck in the past” at times if that makes sense?)
Things He Likes: Anything sun related it seems, sunflowers, yellow flowers, gold items etc. Yellow, Gold, Reds, and Oranges seem to be colors He favors (and of course Lapis blue). For offerings: oranges, orange juice, sun flower seeds, the usual bread, water and beer, artwork, devotional writing, jewelry, cheese pizza (it looks like a sun disc). But I think that the most important offering and activity you can do for Him is following ma’at, since its important to Him. (He is also very fond of bees)
