Well, as a matter of fact they do. Both the law of karma and law of attraction are two sides of the same coin. Both these laws cease to exist in isolation.
Let me explain.
We all know that the Law of Attraction says that Like attracts Like. So if you attract something to yourself then you must get it. Of course, that is exactly what the Law of Attraction says, at least to the best of my knowledge. But does the gratification happen instantly? Well, no, almost never, if at all.
Law of Karma and Law of Attraction explained further...
There is a time lag. This is the time it takes for the law of attraction to attract desirable circumstances and opportunities in your life which you can use to wipe out the past karma to make way for what you attracted. So, essentially the Law of Attraction attracts whatever is required for you to change your Karma, it doesn't go around the Law of Karma, never does that happen.
Similarly, when you attract something (law of karma and law of attraction) by your thoughts, it still takes the requisite amount of time gap for the Law of Karma to turn favorable to you. The amount of time required is driven by the Law of Karma and nothing else, assuming Law of Attraction is already favorable to you and is attracting positive elements using the Law of Karma and Law of Attraction to benefit you.
There is absolutely no way that you can circumvent either of the two laws, the law of attraction and law of karma. Both are essentially twin sisters or like two sides of the same coin. One can only help convince the other to help you when they get together as a team. However, neither will be able to solve your problems magically on its own.
Similarly, when you do good deeds according to the law of karma and law of attraction, then you essentially manifest good karma which makes way for positive thoughts and a positive lifestyle which is in accordance with the law of attraction and law of karma and together they encourage each other to benefit you in all spheres.
Of course, it is possible that somebody has a medium score in the law of karma according to God and high score in the law of attraction, his karma points, that is. Such a person is likely to be better off than somebody with a similar karma but lesser faith in the law of attraction. But when you look at it at an even deeper level, that means beyond the seven planes of existence then the Law of Karma essentially equals the Law of Attraction and one can't have a different point system for the two. However, this is beyond the scope of this blog post.
The point is that the law of karma and law of attraction are inter-related and inseparable and work together to make a person what he finally becomes!
If you delve into the deeper meaning of Dera Sacha Sauda Sirsa Chief' Sant Gurmeet Ram Rahim Singh Ji Insan's Satsangs (website http://www.DeraSachaSauda.org ) then this is essentially what he means as well, but without clarifying till the last point as that is left for his students to decipher by their faith in the Lord. He too essentially talks about the Law of Karma and Law of Attraction.
