In the Bhagavad Gita the Lord has given many theories to explain the world and the means to liberation from the bonds of avidya, the phenomenal existence.
We try, by the means known to us, to overcome the limitations in the form of hunger, thirst, wants and desires, and sex and power urges. Sometimes we gratify those desires, wants and urges, sometimes we inhibit them. But in either case there is no satisfaction, and our life is a chain of want of abiding delight and suffering caused by the ingratitude of our friends, our losses and our disappointments.
In the course of our struggle against want, disease, losses and old age our dear ones leave us, and our faculties become weaker and weaker.
The animal world does not seem to suffer as much as man does. These handicaps and obstructions in our life can be utilised for a higher purpose. In the expansion of our heart, with our intellect devoted to the pursuit of spiritual truth and the exercise of selfless benevolence, we feel a certain refined satisfaction. These are the means to a higher end, and their crown is devotion to God and the practice of Dhyana, meditation, in a tranquil and purified mind.
At the end of the Gita Shastra, the Lord sums up the supreme means to liberation: “The Lord dwells in the heart of all beings … Seek refuge in Him with all your being…”
This verse is, according to some great Acharyas, the soul of the teachings of the Gita Shastra.
It is a universal teaching and is found in all the great scriptures of the world.
“Love the Lord with all thy heart, with all thy soul and with all thy might.” ”
Give up all and follow Me,” says the holy Christian Gospel.
