The soul is something which contains the body. The body doesn't contain the soul. The soul, if we put it into modern language, is the entire complex of relationships in whose context this organism exists.
Ahimsa is the attribute of the soul, and therefore, to be practiced by everybody in all affairs of life. If it cannot be practiced in all departments, it has no practical value.
And what if all of animated nature Be but organic harps diversely framed, That tremble into thought, as o'er them sweeps, Plastic and vast, one intellectual breeze, At once the soul of each, and God of all?
If you make it a habit not to blame others, you will feel the growth of the ability to love in your soul, and you will see the growth of goodness in your life.
