Guru Harkrishan Sahib ji spots the Maharani.

Raja Jai had is Maharani disguise herself so as to see whether Guru ji could pick her out. Guru Ji being omniscient was not pleased with the raja but played along and picked out the queen. "The House of Guru Nanak will always confer happiness on those who have unwavering faith. But he, whose mind is in doubt, is not a true believer. He who is proud and considers himself exalted must ultimately fall. Devotion, which is like rain, rests not on lofty peaks"
