Success (S) = Effort (E) x Prarabdha or Destiny (D)
In the above equation the fixed portion of Prarabdha karmahas been translated to destiny because it refers to that component of the past karma which already has begun to bear the fruit and nothing can be done about it.
In this equation S can range from 0 to 1. When S equals zero, there is zero success, or complete failure. When S is equal to 1, there is 100% success.
Likewise, E ranges from 0 to 1. When E equals zero, there is zero or no effort. When E equals 1, there is 100% effort.
Similarly D also ranges from 0 to 1. If D equals zero, there is only past bad karma. If D equals 1, there is good fortune or good karma.
Now look at the equation: S = E x D again. If 1 is substituted for D and zero for E, S will be zero. This means, even with the best destiny due to one’s past best karma,success is directly proportional to one’s efforts, your free will to work hard or not.
Thus, the only way S can be equal to 1 is by having both D (destiny) and E (individual effort) equal to 1. Therefore, it can be concluded logically that destiny or Prarabdha karmaalone cannot lead to success unless effort is maximized.
Again, from the equation of success, it follows that if D is equal to zero, S will be equal to zero, even if E equals 1. This is the power of one’s predetermined destiny. Bansi Pandit* therefore concludes “Since a person’s destiny in the present life is based on his karma from previous incarnations, he has no control of impact of his predetermined destiny on his present life. All he can do ismaximize his effort in the present life. Although the impact of individual’s destiny cannot be underestimated, it is the effort that he must control by utilizing his free will. On a broader level, this means that one must do the best one can and not worry about the results.”
