Gurudev, can a person who doesn't believe in the idea or reality of God be spiritual?
Yes, sure! One doesn’t need to have a particular belief system to be spiritual. One simply has to have the spirit of enquiry, then you are spiritual.
You need to be bubbling with enthusiasm. If you are aware of the cosmic reality, that there is much more to be known and you know very little, then you are treading the path of spirituality.
If you have bubbling enthusiasm, joy and you are serving people, sharing the joy, that is part of spirituality. A deep sense of satisfaction, a sense of completeness is all part of spirituality.
