Shiddat is used to describe the intensity of something.

Baadlo mein har kisi ke vaaste hai koi boond
Shart yeh hai utni shiddat se koi pyaasa to ho
– Rajesh Reddy

The clouds hold drops (of water) for everyone,
The condition is that one shows an extreme and intense thirst.

The metaphorical meaning is that the universe has the capacity to fulfill everyone’s dreams and desires, one must just want something with such a fierce intensity that it compels the universe to give in.
