"Every learned man knows very well that attachment for the material is the greatest entanglement of the spirit soul. But that same attachment, when applied to the self-realized devotees, opens the door of liberation.
"The symptoms of a sadhu are that he is tolerant, merciful and friendly to all living entities. He has no enemies, he is peaceful, he abides by the scriptures, and all his characteristics are sublime."
(Srimad-Bhagavatam, 3.25.20-21)
