Greatness will come ...

Ba-qadr ranj yaabi soruri raa
Ba-shab bidaar budan mehtari raa

You'll experience bliss to the extent of the pains you undertake.
Greatness will come if in the night you keep awake.

- Baba Farid

O Mercy of the worlds!

"O mercy of the worlds! You are the intercessor for the sinners. On account of your infinite generosity, mercy and magnanimity, intercede for us on the Day of Judgement. O, who has come to all the worlds as a source of mercy, help Zayn-ul-‘Ābidīn! Who is caught in trials and tribulations by the party of the oppressors and beseeches your help"
- Imam Zayn ul Abidin
