The individual soul is forever a servant of the Supersoul and therefore, his reletionship with the Supersoul is to offer service. That is called Bhakti-Yoga or Bhakti-bhaava.
We are not here for happy material life, we are here for selfless service and shelter.
When you take a position, you have to accept responsiblities.
Integrity means to be honest, to be truthful and to make great sacrifices for the welfare of others.
Do not think that if you surrender your mind & senses in remembering Krishna, You will be loser. You will not lose anything, except bondage, frustration and suffering.
By natural arrangement, every one is supplied their food & shelter by the Lord, so nobody should encroach upon the right of living of others.
You are where your mind is.
Even a small service performed with love & devotion pleases Lord Krishna.
Hammer every thought in your mind thinking of how to serve Krishna.
By the grace of the spiritual master the cloud of the mercy of the Personality of Godhead is brought in, and then only, when the rains of Krishna consciousness fall, can the fire of material existence be extinguished.
