The Bhagwad Gita is a Scientific handbook that takes you from spiritual infancy to heights of perfection. It resonates with everyone because of its mind-stretching quality.If you think that to be assertive is the way to go,the Gita speaks of softness.If non-action seems to be the option the Gita prescribes action.If grasping will help you to acquire more of the world,it counsels you to let go -lose it,to gain it.
The Gita first lesson is on importance of the intellect.We have two gifts-choice of action and intellect.Choice is  given and intellect we have to develop.Nobody understands the importance of the intellect and the need to strengthen it.Hence people are making choices with a weak intellect.The mind is the seat of emotion,impulse,like and dislike.Intellect discriminates,judges,discerns,weighs the pros and cons and arrives at a decision.Mind is irrational,intellect is rational.The purpose of life is to make the mind work for you and not against you.
