Karma Yoga breeds Despondency / Fatalism.
Sure, it can (for the misinformed, or those who wish to
adopt a piecemeal approach to Karma Yoga, which it is not).
Karma Yoga pre-supposes the doctrine of rebirth and it is
here that faith in this belief is paramount. Karma Yoga pre-supposes:
We are the product of our stored impressions (samskaras) formed on
account of past karmas-from our evolution to the present stage.
Our free will of the present life presents us an opportunity to
exhaust our past impressions and reduce / exhaust creation of fresh ones.
This process of using our free will is an important factor in determining
our peace quotient as well as how fast we reach the ultimate destiny of all
mankind which is often referred to as Enlightenment or Supreme Bliss.
If one understands the above principles in sufficient
depth, he/ she would realize that there is no room for despondency. Despondency
and fatalism result in the building up of more karmas / impressions and bring in
Tamas, which actually takes us away from the process of
purification and our upliftment.
The only way out is by using our life & free will as an
opportunity to exhaust as many archetypes (subtle impressions) & karmas as
possible by living in the spirit of karma yoga.
