Knowledge is just the collection of facts and data. The wisest are those who have transformed themselves from within. The ancient sages have prescribed a clear pathway to bridge the gap between knowledge and wisdom.
There are three stages of gaining wisdom - shravana(listening), manana(reflection) and nidhidhyasana. The third step comes, when you have achieved the former two steps. After listening or reading, you must experiment it. Then, you are ready to integrate the knowledge into your system. Most people stop with just the intake of knowledge. It becomes wisdom only when you live what you have listened.
Before you take on the world, you have to win against your most powerful opponent - you! You have set your own limits. The Bhagwad Gita helps you to understand yourself, identify your strengths and leverage them to overcome your weaknesses. Like us, Arjuna also spoke words of wisdom, but was unable to live them.
We have to find our true purpose in life. Life cannot be just earning money, getting settled, going on vacations, growing old and dying. And till then, we are not satisfied and happy because we have not lived our true purpose in life.
We should strive to changing our own self to changing others. Shree Krishna bridges the gap between knowledge and wisdom. We need to find the most effective path towards the goal of total fulfillment. In Bhagwad Gita Shree Krishna explains that wisdom is the most powerful weapon as it burns our past and present karmas. A yogi manifests this wisdom within himself through constant practice and dedication.
