Premanand Maharaj Ji
How can I turn my office work into spiritual practice?
Offer your work hours to Bhagwan
Do your duty and try to earn, and offer your working time to Bhagwan. That offering becomes karma yoga, action as worship.
Keep dedicating your time to Bhagwan. This makes your work an offering to Bhagwan, and that becomes karma yoga and leads to attaining Bhagwan.
