The mission of life is to revive the dormant divine consciousness in every living being.
One thing is certain; uncertainty of our life.
To attain freedom from material life, one must take to Krishna consciousness.
Srimad Bhagavatam 6.5.16,
Materialistic way of life is always fearful because at every step there is danger. Materialistic Life is full of anxieties and fear.
Srimad Bhagavatam 7.6.5,
What is the value of a prolonged life which is wasted, inexperienced by years in this world? Better a moment of full consciousness, because that gives one a start in searching after his supreme interest.
