Spiritual Progress Vs. Cult of Personality

Yoga is not Buddhism, but there is a belief in Buddhism that the journey is far more important than any personality or cult of leadership that may form. This is valid when applied to the practice of yoga, especially amidst all the "guru" scandals that have arisen in the past 100 years, not the least of which is Bikram. The practice and the journey are more important than any single teacher or personality.

"Throughout his life [Gotama, the Buddha] fought against the cult of personality, and endlessly deflected attention of his disciples from himself. It was not his life and personality but his teaching that was important... If people started to revere Gotama the man, they would distract themselves from their task, and the cult could become a prop, causing an unworthy dependence that could only impede spiritual progress."
