In this quatrain, Attar emphasizes that the true spiritual path lies within the 'veil of the heart' rather than in the external world. He posits that stepping outside one's internal spiritual boundary (the 'veil') is the essence of error, leading to a state of being 'diminished and lacking.' The poem critiques the restless, 'crooked' movement of those seeking truth 'left and right' in the external world, urging the seeker to find stillness and direction within their own heart.
