My mother said It is difficult for persons of impure souls to know Mahadeva. These men are incapable of bearing him in their hearts or understanding him at all. They cannot retain him in their minds. They cannot seize him nor can they see him.
अम्बोवाच दुर्विज्ञेयो महादेवो दुराधारो दुरन्तकः। दुराबाधश्च दुर्ब्रह्यो दुर्दश्यो ह्यकृतात्मभिः॥
