Just like a paper boat floating in water can be destroyed any moment, similarly this human body can be destroyed any moment. However, if we take shelter of Krishna, we can go beyond this ocean of material existence.
The tendency in this world is that something has to thoroughly shake us up for us to really take shelter of the Lord.
By surrendering and praying for the causeless mercy of the Lord, the devotee can progress on the path of complete self-realization
Srila Prabhupada’s purport on Sri Isopnishad Mantra 18
The real fiber which is preliminary for entering into the spiritual realm of God is the art of surrender and discipline is the prerequisite to learn the art of surrender.
We are not here for happy material life, we are here to serve and surrender.
One only has qualification to receive instruction from guru where one surrenders.
