If you want others to love you, you must first love others. If you benefit others, naturally they will benefit you. The cause and effect of karma is as simple as this. The Vajrasattva purification practice, which is more powerful than negative karma, can prevent you from experiencing the problems that negative karma would otherwise bring you. Thus, the practice of purification is one of the most important solutions to our problems and is extremely necessary, even for people who believe that we have only one life. If you don’t want relationship problems, business failures, illnesses such as cancer or AIDS, notoriety, or criticism by others, the practice of Vajrasattva is extremely important—both for those who accept the existence of reincarnation and karma, and for those who do not.
Doing Vajrasattva retreat is not simply about reciting the mantra and saying some prayers. It is about making the practice effective for your mind, making it the quickest, most powerful way to transform your mind. Experienced meditators have advised that, in general, it is more important to put your everyday life’s effort into the practice of purification. This is the way to attain spiritual realization.
Vajrasattva Recitation at Night
Before you go to bed each night, recite the Vajrasattva mantra to prevent whatever negative karma you have created that day from multiplying. If you don’t purify it in this way your negative karma will keep doubling and re-doubling day by day, week by week, month by month, and year by year up to the end of your life, and even one day’s negative karma will become as huge and heavy as a mountain—in time, even one atom of unpurified negative karma can swell to the size of the earth.
Even though you may not necessarily create particularly heavy negative karmas, since unpurified negative karma increases exponentially in this way, even one small negative action can cause you to be reborn in the lower realms and experience great suffering for many eons. And because in the lower realms you continually create more and more negative karma, it is extremely difficult to be reborn back into the upper realms, which makes it almost impossible for you to practice Dharma. Therefore you must purify your negative karma every day.
Since practicing the Vajrasattva recitation-meditation at the end of the day prevents negative karma from multiplying it is an incredibly powerful method. It makes your life very light and easy and keeps you happy and peaceful inside—in your heart and in your inner life. Furthermore, it purifies not only that day’s negative karma but also that created in this life from the time you were born and in all your previous lives as well.
Purifying negative karma makes it much easier to attain liberation and actualize the path to enlightenment. It also decreases your suffering and any obstacles that might arise. Purifying negative karma means that you won’t have to experience the many eons of suffering in the lower realms that result from not purifying even one negative karma, and you won’t have to experience again and again without end the four suffering results that arise from each unpurified negative karma.
The conclusion is that even if you have completed the preliminary of reciting 100,000 Vajrasattva mantras you can’t just stop, relax, and say, “I’ve finished my Vajrasattva preliminary practice. Now I don’t have to recite that mantra any more.” You need to keep doing the long Vajrasattva mantra at least 21 times or the short one at least 28 times a day in order to keep purifying your negative karma and prevent it from multiplying.
