Swami Vivekananda,
The Complete Works of Swami Vivekananda…
“ Gradually the Self will be realised like a fruit on the palm of one's hand. This realisation alone is the soul of religion. Everyone can go on abiding by some observances and formalities. Everyone can fulfil certain injunctions and prohibitions but how few have this longing for realization! This intense longing—becoming mad after realising God or getting the knowledge of the Self—is real spirituality. The irresistible madness which the Gopis had for the Lord, Shri Krishna, yea, it is intense longing like that which is necessary for the realization of the Self! ”
