He must purge his breast

“…He must purge his breast, which is the sanctuary of the abiding love of the Beloved, of every defilement, and sanctify his soul from all that pertaineth to water and clay, from all shadowy and ephemeral attachments. He must so cleanse his heart that no remnant of either love or hate may linger therein, lest that love blindly incline him to error, or that hate repel him away from the truth…”
– Baha’u’llah
