"In the "Treta Yuga" Lord Vishnu descended on earth as "Prince Rama". He was looked upon as God embodied on earth. Not only were human beings devoted to Him, but also were there many from the animal kingdom. One of those was a crow.
One day Lord Rama and his younger brother Lakshmana were walking beside the Lake Pampa. Lakshmana saw on the other side of the lake a large crow, behaving very strangely. Crow would run up to the water, look at it, bend its head, and then run back into the forest without drinking the water. Lakshmana saw the crow doing the same thing many times. So Lakshmana (who had great respect for his brother's opinions) asked Rama what he could make out of such a behavior of the crow. Why should a bird act like that?
Lord Rama gave one look at that crow and said, "Oh Lakshmana, I can tell you about it: this crow is very devoted to me -- so much so that he is chanting my name constantly upon his tongue. Just now he is thirsty, quite thirsty. But to drink the water he would have to interrupt his repeating of my name, and he just cannot bear to do that." So such was the devotion of that crow towards Lord Rama that it would always chant & repeat Lord Rama's name."
Among humans Arjuna was a true devotee of Lord Krishna & knew that He was the God of the universe. He knew about all the powers of Lord Krishna & also knew that God in the form of Krishna shall save him & lead him to victory. He was having much faith in Lord Krishna than His army. Due to his faith in Lord Krishna only, ultimately he won the Kurukshetra war while Kauravas (his enemies) lost the war. In the Bhagwat Gita, teachings given by Lord Krishna to Arjuna on the battle field of Kurukshetra, Lord is saying:
"samo ’ham sarva-bhutesu
na me dvesyo ’sti na priyah
ye bhajanti tu mam bhaktya
mayi te tesu chapy aham" (Bhagwat Gita: Chapter Nine verse 29)
"Sri Krishna says to Arjuna: I envy no one, nor am I partial to anyone. I am equal to all. But whoever renders service unto Me in devotion is a friend, is in Me, and I am also a friend to him."
"man-mna bhav mad-bhakto
madhyaji maam namaskuru
atmanam mat-parayanah" (Bhagwat Gita: Chapter IX verse 34)
"Sri Krishna says to Arjuna: Fix your mind on Me, be devoted to me, worship Me & offer obeisance's to Me. In this way, linking to Me, you shall surely come to Me."
mam ekam saranam vraja
aham tvam sarva-papebhyo
mokshayisyami ma suchah" (Bhagwat Gita: Chapter Eighteen verse 66)
"Sri Krishna says to Arjuna: Abandon all varieties of religion and just surrender unto Me. I shall deliver you from all sinful reactions. Do not fear."
"patram puspam phalam toyam
yo me bhaktya prayacchati
tad aham bhakty-upahrtam
asnami prayatatmanah" (Bhagwat Gita: Chapter Nine verse 26)
"Sri Krishna says to Arjuna: If any one offers Me with love and devotion a leaf, a flower, fruit or even water, I readily accept that offering of that devotee."
So let's have devotion towards the God. Let's remember God for some time in our daily life so that we can too generate some "Spiritual Emotion" toward the God. Once that is developed, we shall always find God near us & our life shall be filled with joy, love & ecstasy. So the Devotion to God is the supreme. It removes all the sins of a devotee & removes all the ignorance from one's life.
Jai Sri Krishna.
