Finding happiness from God makes you strong as it makes you abandon bodily passions, consideration for human respect and the love of the self. Seeking happiness from the world tends to make you weak. Happiness from food makes you a glutton, happiness from sex makes you an animal, and happiness from drugs makes you an addict. Happiness from receiving the Holy Eucharist will transform us to the likeness of Jesus, as St. Peter Julian Eymard says.
When your happiness relies on created things rather than God, it can be taken away from you. If your happiness relies on hearing music and you become deaf, you will be sad. If your happiness relies on watching television and you become blind, you will be sad. If your happiness relies on having friends and they abandon you, you will be sad. It is so cost-effective to be happy simply from thinking of God and a silent moment of prayer. Nobody can stop you from praying and being happy by doing it. The saints did it all the time using prayers like the Jesus Prayer for example.
There is no limit how much you have to hear, see and taste to make yourself happy, as more and more will be needed. With happiness from God you will have peace simply from the thought that God loves you. Then you can say with Saint Augustine: “Our heart is restless until it finds its rest in thee.”
