The Lord in Bhagavad Gita prescribed selfless action or actions where do not expect any rewards. In the modern world every business is financially and goal driven. Even if you do good work it goes unnoticed without self promotion.

How can one achieve materialistic goals through selfless action? how can a selfless person get something without asking for it - be it a raise, starting salary, opportunity? What is the way prescribed by the Lord for such goals?
