What can you practice? Can you practice love? Yes, you can do all the actions of love; you can hug somebody, but it does not mean that it is love. It may be just a wolf's hug. Yes, in love, people hug, but that does not apply vice-versa, that when you hug you are in love. Yes, when people love they have certain expressions for each other. That does not mean that by repeating those expressions you are in love.
