Education is the distinguishing mark of humanity.
Sadhana or piety is education. The five-fold structure arises from the five elemental principles, Ether, Air, Fire, Water and Earth, combinations and permutations of which produce the five senses, from which the universe proceeds. The five-ness is essential to the EHV as to sadhana in general. Country and local organizations of Sai movement build their own EHV curricula and share what they have built. From the start, local control and adaptation, all based on the Sarva Dharma Symbol , has been encouraged.
