CHAPTER - 4. HINDU ETHICS-6.2
6. The Foundation - Principles - Of Hindu Ethics - 2.
The Atman or Self is one. One life vibrates in all beings. Life is common in animals, birds and human beings. Existence is common. This is the emphatic declaration of the Upanishads or Srutis. This primary truth of religion is the foundation of ethics or morality or science of right conduct. Morality has Vedanta as its basis.
The first thing you learn from religion is the unity of all selves. The Upanishads says: “The neighbour is, in truth, the very Self and what separates you from him is mere illusion.” One Atman or Self abides in all beings. Universal love is the expression of the unity. Universal brotherhood has its basis in the unity of Self. All human relations exist because of this unity.
Yajnavalkya said to his wife Maitreyi: “Behold, my dear, not indeed for the love of the husband is the husband dear, for the love of the Self is the husband dear.” And so with wife, sons, property, friends, worlds and even the Devas themselves. All are dear, because the one Self is in all. If you injure another man, you injure yourself. If you help another person, you help yourself. There is one life, one common consciousness in all beings. This is the foundation of right conduct. This is the foundation of ethics.
