Do not think something  impossible. It is the greatest heresy to think it. There is only one sin - to say that something is weak - Thus taught Swami Vivekananda

I do not think there is anything impossible. It is the greatest heresy to think. There is only one sin - to say that there is anything weak - Swami Vivekananda taught this

أنا لا أعتقد أن هناك أي شيء مستحيل. فمن أعظم بدعة في التفكير. هناك خطيئة واحدة فقط - القول بأن هناك شيء ضعيف - تدرس سوامي فيفيكاناندا هذا
