“Ennoia’s themes are mediation, communication, magic and knowledge. Her symbols are angels. In Gnostic tradition, Ennoia is the Goddess of knowledge, intention and thought. Through Her all things were designed and manifested, including the angels. Through Ennoia we can learn the art of magic and how to communicate with angels as mediators between us and the Gods.
Today is Guardian Angel Day, a time to give thanks to the angels in our lives – those powers and people who protect, inspire and watch over us. One easily adapted tradition from Spain is that of wearing scarves and bells. These represent the beauty and music angels are said to bear into human life.
Second, take a moment to give back to the people in your life who have been like earthly angels (you know, the folks who bring soup when you’re sick, or offer money when funds are tight). Do something really nice for them, or minimally, light a candle on their behalf asking for angelic blessings in their lives.
Finally, try to connect with your guiding guardian angel(s). During your daily prayers or meditation, ask that power to reveal itself in words comfortable to you. Wait, watch and listen. The angel may reveal itself as the sound of bells or quiet music, with radiant light, or in other manifestations. If the being speaks with you, write down the words and ponder them in the days ahead.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
According to the blog, Prayers and Reflections, “Ennoia means ‘thought’ Sophia in Her high form as Pleromic, is the first thought (so She is the first Aeon, or Pleroma, and the last one as well). Creation happens in the triad of thought, word, and action.” 
“The Ennoia is important in Gnostic Magic, because She is the feminine counterpart or spiritual consort of God. She is the Womb of all manifestation, and thus is similar to the Egyptian Goddess Nut or Nuit. In a psychological (Jungian) sense, She is the archetype of the feminine principle.” 
I came across a lot of interesting information while researching this Goddess; everything from identifying Her with Sophia and the Holy Spirit, as Divine Female – the Wisdom Goddess who assisted in creation to being stripped of Her holiness, portrayed as foolish, conceiving alone without a male consort resulting malformed creatures and “falls” to the “lower” world, into bondage and even whoredom in need of rescuing (see The Ennoia). In an attempt to demote, degrade and overthrow Her, the patriarchy even splits Her, “Through disconnecting from the divine oneness it is also Sophia who has to exist in two forms: Sofia Ennoia i.e. the High Sofia, Neverending One, The Power of the Thoughts as well as the Low Sofia called the Small Sophia or Sophia of Death. In this way Sophia combines two elements: the divine and the human one.”  I even found a few references to Her as being a daughter of Lilith….Not sure if this is a totally different deity or what the deal with that is…a little confusing….
