While traveling on the subway, He ['Abdu'l-Baha] said:
“In man's nature there must be a desire to ascend and not to descend. The underground air is suffocating. It would have been better if we had gone by road above. The Blessed Beauty used to say that it is even a pity that the dead body of man should be buried under the ground.”
- ‘Abdu’l-Baha (July 6, 1912, New York; Mahmud’s Diary)
