Neither of them spoke for a while. Then the king said: “O learned man, you did well. But that is not all that I expected. Study Bhagavat Gita again and come back after few days.” Learned man, bowed in reverence. After few days learned man again came to the king. King told him to explain the same Chapter Nine verse 22 as was chosen on previous occasion. The learned man did his best this time too.
King & the learned man were silent for a while. King asked the learned man “What were you thinking of after finishing your lecture up to this moment?” Learned man said “I was thinking what will be the result this time and what rewards I may receive.” King was much pleased with his honesty. King told him “I don’t doubt your ability. Krishna says that He will take care of the material and spiritual needs of those who constantly think of Him, without thinking of anything else. But you only thought of your reward. So, you did not trust Him!
A learned man like you should perform action without having any concern for the result. Any praise or reward from a king is also immaterial”
In Bhagwat Gita Lord Krishna tells Arjuna to always have faith in Him only as, whosoever, keeps faith in Lord Krishna, He always protects that devotee.
"ananyas cintayanto mam
ye janah paryupasate
yoga-ksemam vahamy aham" (Bhagwat Gita: Chapter Nine verse 22)
"Lord Sri Krishna says to Arjuna: But those who always worship Me with exclusive devotion, meditating on My transcendental form—to them I carry what they lack, and I preserve what they have."
So If a person has the above said assurance of the God, then one should make a resolve that one shall not let God slip out of his/her mind till he/she lives on this earth. Do not let anything else take control of your mind & let God be always on your mind. By doing so God shall always be with you in all of your circumstances & shall protect you always from all troubles of life. Then God shall be your Savior always.
Jai Sri Krishna
