I stopped seeking new Spiritual teachers and texts around 2016. There are many knowledgeable Spiritual teachers not listed that may be of value to you. Most Spiritual teachers have free YouTube videos so you can get a sense of who they are. As always, how you feel is your best guide with respect to what information serves you.
If you have been studying New Thought/Ancient Wisdom for a while, please consider reading The Way of Mastery by the Shanti Christo Foundation. You can find study groups though their web site. This one book changed my life more than any other.
The Laws of Spirit by Dan Millman is a fiction book that succinctly and beautifully describes the Spiritual Nature of reality.
Studying the Law of Attraction is crucial in my opinion. Esther Hicks (who channels Abraham) is a great resource. She has numerous YouTube videos.
