Todays' Thought
Be content with what you have; rejoice in the way things are. When you realize there is nothing lacking, the whole world belongs to you.
- Lao Tzu
जो तुम्हारे पास है उससे संतुष्ट रहो, चीजें जैसी हैं उसमे आनंदित रहो, जब तुम इस बात का एहसास कर लेते हो कि किसी भी चीज की कमी नहीं है , पूरी दुनिया तुम्हारी हो जाती है |
