Along with changes in the wavelengths of objects, there are corresponding changes in the external surfaces of physical structures. Vibrations, sound, form and colour also change.

Demonstration

[One day two sádhakas [spiritual practitioners] were sitting on Bábá’s lap. Another sádhaka clearly saw that two living human beings were sitting on Bábá’s lap. The next moment, when, as directed by Bábá, he looked at those two figures, he saw, to his utter amazement, two stone chips. Later on, he began to mark, with still greater wonder, that those two figures were successively changed into (1) two terrifying giants, (2) two ferocious tigers, (3) two human skulls, (4) two monkeys, (5) two mangoes of leḿŕa variety, (6) two sweet potatoes, (7) two grains of paddy, (8) two grains of cúŕá [beaten rice], (9) two goats, (10) two dogs, (11) two lotuses, etc. Later on, when the observing sádhaka joined hands with them, all three were transformed into (1) three one year-old children, (2) a three-legged table, (3) a chair, (4) a copy of Subháśita Saḿgraha Part 1.

This series of changes occurred due to changes in the wavelengths of different entities.
