There is no happiness like Nirvana.

Natthi rāgasamo aggi, natthi dosasamo kali; 
Natthi khandhasamā dukkhā, natthi santiparaṃ sukhaṃ.

There is no fire like lust,

There is no ill-fortune like hatred;

There is no sorrow like this bodily existence, 

there is no happiness like Nirvana.

Dhammapada, 202.
