Actual happiness is that that's permanent. Real happiness can't come from humans, locations or material objects, because they themselves are transient.
Temporary means something that gets destroyed. Therefore, happiness taken from temporary things offers temporary happiness.
Example: If one buys a car they turn out to be glad and if it meets with an accident they will come to be unhappy. This indicates that whenever we try to get happiness from materialistic things, it leaves us with sadness.
Only a everlasting entity can provide you with everlasting happiness. That entity is your own self (soul). Bliss is the nature of your true self, so if you achieve it, you will have happiness under all the circumstances.
The purpose of human start is to acquire the knowledge of self. You can attain the knowledge of Self through the Self Realization process performed by Gnani Purush (Enlightened one) and can experience permanent bliss within.
