Long before Aurobindo, scholars were disputing which path to Godhead – the Four Noble Paths, Bhakthi, Jnana, Karma, Raja Yogas – was greater than the other.
Aurobindo stressed that all paths are different branches of the Supreme Path, the Integral Yoga.
Universal Love is the quality needed for Bhakthi Yoga. Psychic control for Raja Yoga. The discriminatory intellect for Jnana and Selfless Action for Karma.
Unless an aspirant develops all these qualities, how can he be eligible for Self Actualisation ?
Integral Yoga, therefore, becomes one of the many ways for Self Realisation
