From Lama Zopa Rinpoche advice:
“It is especially good to recite this mantra before going to see important people or participating in important meetings where you want the people present at the meeting to listen to you and do what you say. This mantra also can help for success in business and it brings wealth. In the text(from the Kangyur), it says to recite this mantra three times each day.
“Buddha taught such things because his omniscient mind knows what methods best fit each sentient being. Out of his great compassion, Buddha gave various mantras to help to remove the sufferings of sentient beings. He showed these various methods while showing the unmistaken path to become free from samsara and achieve liberation and the unmistaken path to achieve enlightenment.”
