Human nature is that everyone essentially wants to love and be loved. If we show affection people open up and we can disarm them of their prejudices against us.
Love means reciprocation. Therefore, you can’t love buildings or cars or money because there is no reciprocation.
Pure love of God is our nature, but we are so much diverted, so much distracted by the externals that we’ve forgotten that it’s our essence.
Seeing other people in terms of their desires rather than your own is the basic principle of loving them. Whenever there are differences, be respectful.
