Karma, Bhakti, Raj yoga are not the means to Self-knowledge or Brahma Gnana or Atma Gnana.

Karma, Bhakti, Raj yoga are not the means to Self-knowledge or Brahma Gnana or Atma Gnana. Mixing them up and trying to assimilate ultimate truth is impossibility. 

There is no need to practice to devotion, karma and raja yoga because they are not the means to acquire Self-knowledge or Brahma Gnana or Atma Gnana.   There is no practice as such but perfect understanding and assimilation  is needed. 

  Deeper inquiry, analysis and reasoning revels the fact that, the self is not physical but the self is formless consciousness. Therefore, all the accumulated knowledge, experiences and understanding based on physical self or ego or waking entity are falsehood based on the false self, within the false experience (waking).   Thus, whatever is based on the waking entity is bound to be falsehood because waking experience itself is false hood.   Since many teachers and teachings are based on the false self (ego or waking entity) and they consider the false experience (three states) as reality, they are incapable of grasping the witness, which is within the three states, but it is without the three states.
