All life forms are part of you – this is the truth. Please understand, if I take handful of clay and understand it thoroughly, then, I know all the clay on the planet earth. Same way, you are life.
Looking at the life larger than your lifestyle, planning for your life larger than your lifestyle is Dharma. It means your decisions are not made just centered on you.
If the basic facts with which you make all decisions of your life are in tune with cosmic goodness and the larger vision of life, you are flowing with dharma.
