“During the Mahabharata war between the Pandavas and Kauravas, Lord Krishna, took the decision not to fight from any side or lift any type of arms. But Lord Krishna broke His promise for His devotees. Duryodhana once incited Bhishma that he was not fighting to his best of the ability as the Pandavas were his lovely grandchildren. Bhishma got very disturbed on this charge and made a declaration that the next day he would kill all the Pandavas.
Bhishma, also made another commitment that he would kill Arjuna that day or he would end up giving his life. Bhishma fought very fiercely and in the fight, Arjuna’s chariot got broken. At that time Arjuna became completely unarmed and helpless. At that time Lord Krishna took up the chariot wheel and went straight to Bhishma so that he could save Arjuna. At seeing, Lord Krishna coming toward him, Bhishma happily threw his weapons away. Lord Krishna by this act of running with the chariot wheel, broke His promise, not to carry any type of arms & hence He saved two of his great devotees (Arjuna & Bhishma) from perishing.
So in this way Lord Krishna could break His promise but he would never break his devotee’s promise. So any person who has resorted to Lord Krishna will never be destroyed & Lord will protect him always."
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.
'Ye tu srvani krmani
myi sanyasya mat-para
maam dhyayant upasate '
bhavami na-chirat parth
mayy-avesita-chetsam ' (Bhagwat Gita: Chapter XII verse 6-7 )
'Lord Sri Krishna says to Arjuna: Those people, who worship Me by surrendering all their activities unto Me, are always devoted to Me, always meditate upon Me, Having always fixing their minds upon Me, O Parth - to them, I swiftly rescue from the ocean of birth and death.'
"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."
yo mam smarati nityasah
tasyaham sulabhah partha
nitya-yuktasya yoginah" (Bhagwat Gita: Chapter Eight verse 14)
"Lord Sri Krishna says: Whosoever, always & constantly remembers Me with undivided mind; by that person, I am easy to obtain, O Arjuna, because of his constant engagement in the devotional service to Me."
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
