Question

Which school of yoga asks its practitioners to wear white

Answer 1

It is the Healthy, happy, Holy Organization which taught their practitioners to wear white clothes. The purpose of this is to expand the auric radiance by at least one foot. A strong aura gives them a solid identity and projection so negative influences are filtered.

Answer 2

Kundalini Yoga asks its practitioners to wear white.

The reason behind wearing the white is that it is believed by them that it expands our auric radiance by at least one foot. Harbhajan Singh Khalsa was the first person who started the Kundalini Yoga and introduced white color to the yoga performers. He was also the founder of "Healthy, Happy, Holy Organization".
