So if you shall put God first in life before anything then your horizon of thinking shall go on expanding to infinity. By having such thinking & devotion to God, you shall be able to understand the God better. As everything in this world has originated from that single source called God only so to keep Him prime & then make your life secondary to God, shall make everything valuable in life.
So you should first gain God in life, and then gain wealth; but do not try to do the contrary. If, after acquiring spirituality & turning your mind towards the God, you lead a worldly life, you will never lose your peace of mind.
Just when you go to a new city, you first secure a comfortable room for your rest at night, and after keeping your luggage there, you feel free to go about the city for sightseeing. Otherwise you may have to suffer much in the darkness of night to get a place for your rest. Similarly, after securing your eternal resting place in God, you can fearlessly move about doing your daily work. Otherwise, when the dark and dreadful night of death shall come, one shall have to encounter great difficulties and sufferings.
Below are few verses of Bhagwat Gita also explaining that God is supreme:
"mattah parataram nanyat
kincid asti dhananjaya
mayi sarvam idam protam
sutre mani-gana iva" (Bhagwat Gita: Chapter Seven verse 7)
"Sri Krishna said: O Arjuna, there is nothing else besides Me in this world. Like clusters of yarn-beads formed by knots on a thread, all this world is threaded on me.
"yac chapi sarva-bhutanam
bijam tad aham arjuna
na tad asti vina yat syan
maya bhutam characharam" (Bhagwat Gita: Chapter Ten verse 39)
"Sri Krishna said: O Arjuna, I am the generating seed of all existences. There is no being—moving or nonmoving—that can exist without Me."
So let's Cling to God & have faith in God. Let God come first always before any other thing in our life. As God is supreme & controls everything, so in this world everything has meaning because of God only. Let's all pray to that supreme, divine, all powerful God only. In this way God shall deliver us from all the miseries of life & shall protect us always in life.
Jai Sri Krishna
