The life of material existence is just like Hard Wood, and if we carve Krishna out of it, that will be success of our life.
If we want to attain the sea of our aspiration, we must persever in our goal and never be discourged by the inevitable obstacles that come in our path. All impediments are like rocks in the river of life. We should flow with them and never give up. With the Lord's mercy, there is always a way.
Choose the path & move in direction of Authorised Spiritual Movement. Success is guranteed.
We Should know in perfect consciousness that human life is bestowed upon the conditioned soul to achieve spiritual success and the easiest possible procedure to attain this end is to chant the holy name of the Lord. – Srimad Bhagavatam, 02.01.12.
Success of our activities is when we have absorption in God.
If at the time of death one can remember Krishna, one’s life is successful.
Srimad Bhagavatam 10.1.5-7,
