I will use Vipin Gupta’s metaphysics to explain the significance and importance from the
first principles.
Mangalam means “whiteness of future” springing the wish one wishes without limitation.
The limitless wish is a wishable wish, because one must make a wish without hesitation
which limits the action necessary to realize what one is wishing. “Wishable wish” is
Bhagwan Vishnu.
Mangalam Bhagwan Vishnu means “wishing system”, that is springing wishable wish.
Thus, this mantra orients one’s actions towards fulfilling the wish with 100% confidence and
conviction of realizing the goal of one’s wish.
