The Lesser Janyati are the next set of holy beings beyond the seven Great Emanations of Dea, the Greater Janyati. They are also very important to Filianism.
They oversee various things, and as such can help in differing ways. Some examples would be Sai Werdë whom you may wish to work with to help you improve your own werdë and another could be Sai Anthea to help you meditate on the beauty of the world.
It would be recommended to approach the lesser Janyati respectfully to learn and grow more as a person, and to further your own spiritual progress. Spend time to pray to, meditate with, and learn what you can about them.
Also included, but generally not named, would be the guardian janya for each soul on earth. Your guardian janya is your protectress, and can and should be called upon to learn about and to help guide you.
