There are couple of shloka’s from Gita that resonate deeply with me. One such is shloka 34 from chapter 9. It says:
manmana bhava mad-bhakto
mad-yaji mam namaskuru
mam evaisyasi yuktvaivam
I also like the translation of this shloka by Eknath Easwaran in his book “The Bhagavad Gita for Daily Living – Vol 2“. He writes:
Fill your mind with Me; serve Me; worship me always.
Seeking me in your heart, you will at last be united with Me
This is the refrain of the entire Bhagavad Gita. The Lord sums up the supreme secret of the spiritual life in one word manmana: “Let your mind be filled with Me.” Let your heart dwell only on the Lord and let nothing else distract you. In your dreams, see the Lord; in your sleep, hear his voice. Under no circumstances must you ever forget him.
In the deeper stages of meditation, the Lord will put you to some simple tests to see if you have unified your consciousness in him. He may strike a great blow at you, and when your whole being is agitated, he will say, “Now let me see you meditate.” It is stiff honest test. The mind may rise in tides of turmoil and object, “How can I meditate when you have struck at me like this? I am completely stunned.” If that is so, you haven’t passed the test. But if you have been meditating steadily and enthusiastically over a long period of time, your mind will remain centered on the Lord, no matter what blows life deals you. Whatever reverses come your way, your heart will always be filled with love. Then the Lord will say, “You pass.” When he says that all your problems pass too.
Under no circumstances, should we forget the Lord alone is worthy of our deepest love. We should never sacrifice our meditation for the sake of any other interest. When we base our life on meditation, our health, our security, our intellectual and creative capacities have to improve; there is no alternative. If we try in this way to fill our hearts with love for him, we will be united with him without any doubt at all.
