As mentioned above, you have not dug deep enough which is understandable given the enormous wealth of his vast and all-comprehensive literature. If you want to read all of them at one place it is Savitri. However the AIM has published an issue or two on Sri Aurobindo life, especially Footprints of God which touches upon some of the major realisations.
Of course even if none of his experiences were known, Sri Aurobindo would be so lovable. One has to only see what he has been doing and why to feel a spontaneous love and gratitude towards him. He is so full of Compassion, so adorable. Never has there been one who has loved God and Man and Earth, sacrificed so much with such love and Divine Compassion. What more is needed to love and adore him?
Affectionately,
Alok Da
