Can meditation and positive thinking really change my karma?

First of all, let’s understand a bit about the science of karma, in this regard
We have already sown seeds of karma in the past life. And in this life, we get the fruits of those karma. If we have sown bad seeds of karma in our past life, then in this life, it shall bear bad fruits, and if we have sown good seeds of karma in our past life, then in this life, it shall bear good fruits. The fruits of karma are inevitable. We bind karma through our intent. So for instance, if we have made an intent to eat junk food in the past life, then in this life, we will eat such food and then fall sick.

How do we change our karma?
To change our karma, we must first know what karma we have bound in our past life.
Therefore, the Enlightened One suggests:
“We do not know what will happen - whether we will eat for sure and whether we will fall sick for sure. After it happens, we will know. If we have the knowledge in this life that by eating junk food, we can fall sick, then maintain awareness. Yet, if circumstance so happens that we end up eating junk food, then we will experience that.

We want to keep in our awareness the knowledge that this thing is harmful. To do or to not do is not in our hands. From how things happen, we will gain experience. We will always maintain awareness. For instance, maintain the awareness that, ‘I want to eat less (to keep my stomach light)’ or ‘I want to resolve every circumstance that I come across with equanimity.’ Maintain that awareness.

If layers of karma are less, we will experience a quick change, if not, we will realize that as well. The fact is that we have to suffer the fruit of every karma. The fruit of karma that has finished, it means there were less number of layers. Therefore, by maintaining awareness, they finished faster. Those where layers are more or karmas are sticky, then it will take time. Yet, we will have to suffer each karma. If the karmas are less, we will realize it, if they are more, we will realize that too. But we want to finish each karma, one by one.

Now, the awareness that we want to maintain is that the worldly self is affected by the suffering caused by karma. I (the Soul) am the knower of that suffering – this is the awareness to keep. To change or stop the relative (worldly thing) is not possible. Whatever seems possible, it is because we have sown the intent to change in our earlier life. This change too is a result of the karma only.”

Now, let’s understand regarding meditation and positive thinking a little…
Meditation is pure awareness. But we do not know about Soul. So how can we do meditation of Pure Soul? Therefore, the person who is realized (Self-Realized) i.e. the Enlightened person can help us realize our Soul. Then, we can remain in the meditation of Pure Soul that, “I am a pure Soul, separate from the worldly self. It is the worldly self that is affected by the suffering caused by karma. I (the Soul) am the knower of that suffering.”

And as far as positive thinking is concerned, it comes with positive vision. Spiritually, the highest positive vision is to see the pure Soul in everyone; and the highest understanding is that only when circumstances come together any task gets completed; no one is an independent doer in this world and therefore no individual is at fault. When we see faults of others, we bind karma. And One who sees the world as faultless, attains liberation.

This is how meditation and positive thinking can help us come out of the bondage of karma completely. So come, let’s go to the Enlightened One, attain Self-Realization from Him and put an end to all the sufferings created as a result of our karma.
