You must approach dating with a pure heart, as that is my heart. Do not lust after your brother or sister, because then you are not approaching him/her motive-free.
Think of how you came to know and love me. It is because I first loved you. For no reason. With no motives. And so you accepted my love. And then returned it.
Dear one, this is how you all are wired. If you play the world’s love game, you will surely lose. You are on my team, the winning team, and if you play by my rules, you will always be victorious.
