Kindness and a good heart are the foundation for success in this life, progress on the spiritual path, and the fulfillment of our aspirations. Our need for them is not limited to any specific time, place, society, or culture.
Samsara - our conditioned existence in the perpetual cycle of habitual tendencies and nirvana - genuine freedom from such an existence- are nothing but different manifestations of a basic continuum. So this continuity of consciousness us always present. This is the meaning of tantra.
Compassion and love constitute non-violence in action. They are the source of all spiritual qualities: forgiveness, tolerance, all the virtues. They give meaning to our activities and makes them constructive. There is nothing amazing about being rich or highly educated; only when the individual has a warm heart do these attributes become worthwhile.
