These three words are used here in a special symbolic sense. Bread for the physical need of man, the animal; Woman for beauty, the mental needs of man, of the intellectual half-man on the way to self-realization; Bridegroom for the Guru or Personal God. The spiritual need of man, of the angel whose two wings of flight are the mind and the body. Man the animal, cannot live without Bread. Man, the mind, cannot be without Woman. And man, the soul, is dead without the  Guru. His hunger makes all the subjective worlds objective. His passion makes all the objective worlds wholly subjective. His ever rising aspirations for the Highest are fulfilled by finding Him, the Guru, the God. Bread ceases to be reality where Woman becomes reality and Woman ceases to be reality where Guru becomes it. When the ‘Guru’ informs man’s both Woman and Bread man has entered the path of discipleship (Sikkhi) and his attitude has regained its lost spiritual balance.
