The Quran mentions the story of Moses and Khidr [a prophet mentioned in the Quran who guided Moses on a revelatory journey], a famous story, in which Moses represents sort of the external understanding of the religion and Khidr represents the inner spiritual understanding of the religion. Moses went on a journey with Khidr and Khidr said, "I will not accept you unless you stop questioning things," which from an external point of view seems strange, but inwardly is very meaningful. This is exactly the question of spiritual guidance.
Seyyed Hossein NasrThe human soul, provided it is pure and strong enough, can contact the unseen in waking life as well as in dreams: all that is required is withdrawal of the soul from the tumult of sensory life.
Seyyed Hossein NasrThe Shariah has many other functions but also protects the tarqiah; it protects the spiritual path.
Seyyed Hossein NasrAt all costs we should avoid considering our love of God to be superior to the love of the other for GodLet us love God and leave it for Him to decide on the intensity and sincerity of our loves, as well as of our differing views of Him
