Each Janya is addressed with an honorific, generally you will see 'Sai', or 'Madria'; the former meaning 'Holy' and the latter meaning 'Mother', but either used as formally addressing a Janya.
Each of the Greater Janyati will be described below, with the first three embodying the heavenly trinity and the second four being the Janya of matter:

There is a great deal more in depth one can get with the Greater Janyati, but we are starting with the essentials here. It is best to learn their names and virtues, and start from there. Pray to them, learn what those virtues teach you about your day to day life, and how you can incorporate them.
