Srila Prabhupada built a home where whole world could live happily !
The fish is never free from anxiety, since big fish are always eager to eat the small fish. All living entities are eaten by bigger living entities. This is the way of material nature.
The Lord is harder than the thunderbolt for the wrongdoer and softer than the rose for the faithful.
Srimad Bhagavatam 3.3.13,
Every time you are passing the test, you are coming closer to Krishna.
