Vajrasattva meditation practice is one of the best ways to remove negative karma from your life. Vajrasattva is the Buddha of sanitization. Through sanitizing our negativity our mind will increasingly become happier, our good behavior will boost and all our mental and physical problems will slowly vanish. During our connection with Buddha Vajrasattva we can reduce the awful behavior in our mind that reasons our troubles.

2. The Benefits of Vajrasattva Practice
If you wish others to love and care for you, you must first love others.
If you help others, naturally they will help you. The foundation and
effect of karma is as simple as this. The Vajrasattva sanitization
practice, which is extra potent than bad karma, can stop you from
experiencing the troubles that bad karma would otherwise bring you.
Thus, the practice of sanitization is one of the key solutions to our
troubles and is very essential, even for people who believe that we
have only one life. If you do not want relationship troubles, business
disappointment, illnesses, infamy or criticize others, the practice of
Vajrasattva is really important both for those who believe the existence
of rebirth and karma, and for those who do not.

3. Doing Vajrasattva retreat is not simply about reciting the mantra. It is about
building the practice useful for your mind, most powerful way to transform your
mind. "Lama Surya Das says that, it is extra important to put your daily life’s
effort into the practice of sanitization. This is the way to reach spiritual
awareness.“
