Premanand Maharaj Ji
How can I stop lying, in business and in daily habits?
Keep a fixed honest price and practise truth slowly
Lying isn't necessary in business: keep a correct fixed price with your profit added, and Bhagwan makes the arrangements. Practise slowly not to lie.
Keep the exact price, adding your profit to it. The Giver is Bhagwan; when you walk on truth, Bhagwan arranges things on his own.
