The spiritual journey is a unique path for each individual. There are no
right, better or wrong path. Be it dogma, as in the world religions or
communing with nature, each soul chooses what they need in this lifetime and will seek out the kind of people and beliefs that can help them on their spiritual journey.

More recently, 2007-8 Eckhart Tolle has come to my attention. "A New Earth" had a strong effect on me and recently I also read "The Power of Now. These two books can help you along the way to more depth and understanding.

"There are many books by Rudolf Steiner that will assist you in developing your spirituality. In particular "Intuitive Thinking as a Spiritual Path". My personal favorite is "the Essential Steiner"

I also highly recommend Wayne Dyer's "Power of Intention" and "Inspiration". There are many other writers who have guided me along the way. Louise Hay, Shakti Gawain's "Living in the Light" ,The Bible, Jane Roberts, The Koran, Confusionism, Gnosticism, Tao Te Chin, Various Buddhist writings, "Be here Now" by Baba Ram Das, Most writings by Alan Watts, philosophers such as Goethe, Plato, Socrates and, Aristotle. A complete list would take pages, but any of the above will help you get either started or continue on your path.
