You cannot become Happy, You can only Be Happy.

The Truth that is to be Realized may be summarized simply as the Realization that no matter what is arising, no matter how many others are present, there is only One Being. This is precisely different from the childish but common religious notion that even when you are alone there is always Someone Else present, Who will look out for you if you do the right thing. True freedom is not a matter of striking a deal with an All-Powerful Parental Deity; no such God exists. True freedom is in the Realization that there is only God and You are That One.

Love does not fail for you when you are rejected, betrayed or apparently not Loved.  Love fails for you when you reject, betray and do not love.  Therefore .. Love.
