Vedanta is a system of thought, a philosophy in its own right. The followers of Vedanta can reach great heights by following its principles; however, it is simultaneously an open school of thought which says that the whole of creation can be seen as God: Sarvam khalvidam Brahman – “The whole of the visible and invisible creation is God.” Vedanta speaks of experiencing the existence of God in each and every thing.
It can begin with your mundane personal problems also. You do not need to have high-flying thoughts to practise jnana yoga. The thoughts can also be material, physical and sensual. Personal difficulties and handicaps can act as a catalyst for discovering your limitations, creativity, force of will and clarity of mind. If you are aware that all these little changes are happening, it is part of the process of jnana yoga. Whether it is jnana yoga, complete yoga or a different system of thought like Vedanta, Samkhya or Nyaya, the underlying factor in all these is the application of wisdom. Knowledge gets converted into wisdom when applied practically in life.
