Your constitutional position is that you are pure living soul. This material body cannot be identified with your real self; nor is your mind your real identity, nor your intelligence, nor false ego. Your identity is that of an eternal servitor of the Supreme Lord Krishna. Your position is that you’re transcendental. The superior energy of Krishna is spiritual in a constitution, and the inferior external energy is material. Since you are between the material energy and the spiritual energy, your position is marginal. Belonging to the marginal potency of Krishna, you are simultaneously one with and different from Krishna. Because you are the spirit, you are not different from Krishna, and because you are only a minute particle of Krishna, you are different from Him.
