Premanand Maharaj Ji
My research work takes the whole day. When do I find time for Bhagwan?
Chant in free time, offer rest time to Bhagwan
Chant the Name in every free moment, and give your full focus to your work when you work. When the work is done, offer that time to Bhagwan.
In whatever time you are free, do Naam Jap (chanting God's name). And when you concentrate deeply on something, remember that even worldly work is not completed without concentration.
