CHAPTER - 4. HINDU ETHICS-3.
3. Ethics, Spirituality And Religion-3
Without ethics, you cannot have progress in the spiritual path. Ethics is the foundation of Yoga. Ethics is the corner-stone of Vedanta. Ethics is the strong pillar on which the edifice of Bhakti Yoga rests. Ethics is the gateway to God-realisation.
Without ethical perfection, no spiritual progress or realisation is possible. A Yogic student or aspirant must be strictly ethical. He must be truthful and pure in thought, word and deed. He must possess excellent conduct. He must not injure any living being in thought, word and deed. He must practise rigidly right thought, right speech and right action.
Every religion has its ethics. The Sermon on the Mount of Jesus and the Ten Commandments contain ethical teachings for the uplift of man. The Noble Eightfold Path of the Buddha is the essence of ethics. The Yamas and Niyamas of Patanjali Maharshi constitute the highest ethics. Manu Smriti, Yajnavalkya Smriti and Parasara Smriti contain the code of conduct for man. The three kinds of austerity of the Gita are nothing but ethics in an intensified form.
