As long as you have attachment to the body and attachment to objects, fear and suffering will be with you. Therefore Krishna told Arjuna to develop his discrimination and rid himself of body consciousness. Only then he would be able to develop integral vision.
Those who see all creatures within themselves, and themselves in all creatures know no fear. Those who see all creatures in themselves, and themselves in all creatures know no grief. How can the multiplicity of life, delude the one who sees its unity?
The soul that is attached to anything, however much good there may be in it, will not arrive at the liberty of Divine union. For whether it be a strong wire rope or a slender and delicate thread that holds the bird, it matters not, if it really holds it fast; for until the cord be broken, the bird cannot fly.
