Wavering and indecisiveness will affect you, if you want to practice Righteousness. If you are not stabilized in the Knowledge of the Self, you will not have a good sense of direction for your actions, nor will you achieve true victory. That is why the Geetha lays so much emphasis on the necessity to know both the kshethra (field or the body) and the kshethrajna (the Knower in the body). Know both, and then, you are entitled to the title, Amrithasya Puthraah: “Children of Immortality.” Through devotion to God alone, this knowledge can be attained. Devotion also purifies your heart and elevates your inner feelings and gives you a broad, universal vision and brings to you the Grace of God. Plants cannot rise up to drink the life giving fluid from clouds, hence the clouds come down and pour as rain.
Devotion and morality are very important for physical health. They free your mind from agitation, and feed it with joy and contentment. –
