Enlightenment (spiritual) yoga" and "karma yoga" are subsidiary. In bhakti yoga, practice centers on the worship God in any way and in any form, like Krishna or Ayyappa. Adi Shankara himself was a proponent of devotional worship or "Bhakti". But Adi Shankara taught that while Vedic sacrifices, "puja" and devotional worship can lead one in the direction of "jnana" (true knowledge), they cannot lead one directly to "moksha". At best, they can serve as means to obtain moksha via shukla gati. Karma yoga is the way of doing our duties, in disregard of personal gains or losses. According to Sri Swami Sivananda,
Bhagavad Gita that "when one sees the entire universe as pervaded by the single Universal Spirit [Krishna], one contemplates, marvels, and falls in love with its amazing glory. [...] Having experienced that Truth oneself, all doubts are dispelled. This is how the flower of devotion evolves into the fruit of knowledge." The "Gita" teaches several spiritual paths – jnana, bhakti and karma – to the divine. However, states Fowler, it "does not raise any of these to a status that excludes the others". The theme that unites these paths in the "Gita" is "inner renunciation" where one is unattached to personal rewards
