Only when we unfold the potentials of the 5 lower chakras (synonymous with the 5 Pandus in the Bhagavad Gita) can we truly over-come the shortcomings of the Ego (I.E. Pride, Lust, Anger and Greed).
This is why MMY called it the Spiritual *Regeneration* Movement initially. It is the unfoldment (regeneration) of these 'powers' locked in the chakras that makes enlightenment possible. http://www.youtube.com/watch?v=U9WndBBdq4M Maharishi lecture and the significance of the chakras: http://www.youtube.com/watch?v=6HHkXoH97r0&feature=g-all-u&context=G2515455FAAAAAAAAEAA
