The more sattva/purity rises in your life, the more easily your tasks get accomplished.
The amount of sattva/ purity in us decides the productivity of our input.
If you put in a lot of effort and the result turns out to be less or below your expectations, it means that there is a lack of sattva/ purity in life.
When we meditate, then our work happens easily. People are unaware of this secret. It is very important to meditate whenever we get time, so that you accomplish your tasks more efficiently and with ease.
