My father always told me that plants and flowers have souls. How else could wise King Solomon have spoken to them? He wouldn't have had much conversation with them if they hadn't had souls! We have to respect all growing things even if we do not understand their ways.
The fitness of our hearts and thoughts to receive God's spirit is like that of violin strings. If they are properly tuned, in harmony with one another, then the touch of the bow produces beautiful music. If not, then there is only discord. Whenever our hearts are truly ready to receive God's spirit, they will produce heavenly airs and joyous harmonies -- both in this life and in the spiritual world.
Once God has become a living reality for us, we simply have to love others. We cannot do otherwise. And once we live in love, we are moved quite naturally and joyfully to serve others. God is love and if we live in union with God, we have the strength and longing to love others. Service is a spiritual activity, the natural fruit of love.
