In the same way, the denizens of this earth are completely unaware of the world of the Kingdom and deny the existence thereof. They ask, for example: ‘Where is the Kingdom? Where is the Lord of the Kingdom?’ These people are even as the mineral and the vegetable, who know nothing whatever of the animal and the human realm; they see it not; they find it not. Yet the mineral and vegetable, the animal and man, are all living here together in this world of existence.
- ‘Abdu’l-Baha (‘Selections from the Writings of ‘Abdu’l-Baha’)
