1.Pravritti maarga is prescribed when one doesn’t have the relevant qualifications to follow the Nivritti
In Pravritti maarga there are 5 varieties of Karma spoken about.
If one wants to make Pravritti maarga
as a saadhana, only Nithya and Naimithika karma should be taken up.
That too unless one performs these duties offering them to a higher altar and accepting the results with equanimity( this is Karma yoga),
ones mind will be tossed around.
The mind being what it is requires
has to hold on to a higher support.
When one thus performs one’s duties
in Karma Yoga attitude the Mind and
intellect become purified and single pointed and become a fit instrument to walk the Nivritti maarga. Hence
Karma yoga is considered as the bridge between Pravritti and Nivritti
