Handicap to work against ...

Hi

From a book about concentration:

It is just as easy to surround your life with what you want as it is with what you don't want. It is a question to be decided by your will. There are no walls to prevent you from getting what you want, providing you want what is right. If you choose something that is not right, you are in opposition to the omnipotent plans of the universe and deserve to fail. But, if you will base your desires on justice and good will, you avail yourself of the helpful powers of universal currents, and instead of having a handicap to work against, can depend upon ultimate success, though the outward appearances may not at first be bright.

I have a problem with that sentence: an obstacle to "work against"? To work against what? I don't understand it.
