The six realms of existence Lately, i'm finding myself very confused. I don't know whether i'm trying to learn new things to become a better person for myself and the world around me, or am i in fact just a ' hungry ghost' unable to satisfy my hunger. I do feel like i'm constantly searching for something, something which even i do not know what it looks like. 

So, my question is; How can i tell if my efforts are for good, or that of an insatiable hungry ghost?

All help is welcome!

If you are worried that your current karmic existence is, or is related to, that of a hungry ghost you should apply the proper antidote. In this case the proper antidote is practicing/developing the first paramita : generosity  Doing such and being aware of your desires and the desires of others can help curb the feeling of constantly searching for some unknown thing. 

As for how to know if your efforts are proper, or for good as you say, I'll turn you to the short and sweet lojung saying "Of the two witnesses, hold the principle one.

Try these things and meditate on them, see if they help, I hope they do. Remember, we all exist in this confusion together, you are not alone in this.
