If we do the right thing with right intent, that is our success.
If at the time of death one can remember Krishna, one’s life is successful.
Srimad Bhagavatam 10.1.5-7,
Choose the path & move in direction of Authorised Spiritual Movement. Success is guranteed.
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.
Success of our activities is when we have absorption in God.
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.
