Swami Ananda Saraswati
Lord Krishna accepting to become a charioteer for Arjuna explains how a teacher is important in our life. He not only teaches what is right and wrong also makes sure one has to abide by what is healthy for one own self and the society. Through his wisdom and power, he makes the life of a student meaningful provided if a student allows the teacher to unfold.
As long as the reigns are in the hands of a charioteer that long chariot is able to negotiate any sort of path that comes on the way. The horses being under the control of the charioteer makes the lord of the chariot not only reach the destination but also relax while travelling. Interestingly, a teacher is a charioteer in our life.
Till the reigns are in the hand of your teacher, he would never let your thoughts waver. Between Truth and Falsehood, Righteousness and Immortality, Security and Insecurity, whenever your mind would lose focus, it would be his endevour to bring you to the right path again. Be it any sort of war or conflict in your life.
A teacher is the best Charioteer.
