We have no freedom not to serve Krishna; we have choice.
One thing is certain; uncertainty of our life.
Godhead is light. Nescience is darkness. Where there is Godhead there is no nescience.
Srimad Bhagavatam 7.8.24,
The aim of real education should be self-realization, realization of the spiritual values of the soul.
Sri Ishopanishad 9,
