One way to Dea is the Path of Love or Devotion, in contrast to the Path of Light, that is, of knowledge or intellectual contemplation.
Starting on the Path of Devotion could not be easier. Our Celestial Mother, like every mother, is always ready to accept the love of Her children.
It is good if you have a picture or a statue of Her. It should be one that you find attractive. One that speaks to you of Her love and beauty. It might be a picture of Mahalakshmi, or a statue of Mother Mary. It might be a picture of Kwan Yin. You might wish to feel the protection of Dea in her mighty form as Sri Durga. Whatever form you love, choose that. Then you can look upon Her form when you talk to Her.
It is traditional also to bring Her gifts. Light candles before Her; burn a little incense. Once you have your picture or statue of Her and have placed some candles and perhaps an incense burner before it, you already have your first Shrine. If you can, it is nice to bring fresh flowers to the shrine and offer them to Dea.
These are very simple things, but simple love always pleases our Mother. Say good morning to Her when you arise and bid Her goodnight when you go to bed. These are the elementary courtesies that a child pays to her mother. It is also considered proper in many circles to bow when you approach Her image or when you pass it.
Another common practice is to offer food to Her before eating it. This is something like saying a simple grace, but the difference is that instead of merely thanking Her for Her bounty, we are giving the food to Her. It is said that she consumes the true essence of the food and that we eat Her leavings, which is the material part of the food. But by Her eating it, the food is blessed and we ourselves taste something of its true essence, which our worldly tongues are unable to do.
These are some simple practices that will start you on the Path of Devotion. If they become part of your life, you will be a devotee of Dea.
