The Best Understanding of KARMAYOGA, GYANYOGA AND BHAKTIYOGA.
Knowing how to drive a car is Karmayog which is the lowest step in which the drivers come. Most people come in it.
Knowing the functioning of each part of the car and having the ability to fix it is wisdom and car mechanics are involved in it.
But knowing the shortcomings of the car and rectifying them, designing an entirely new (Tesla Type Electric) car is devotion.
A person with devotion knows how to drive, repair, because without him it is not possible to build a new better car.
