Similar lines can be found in the Mahabharata..the great Indian epic. This proves that every religion speaks the word of the same GOD.
Heaven’s gate is narrow and minute,
It cannot be perceived by foolish men,
Blinded by vain illusions of the world.
E’en the clear-sighted, who discern the way
And seek to enter, find the portal barred
And hard to be unlocked. Its massive bolts
Are pride and passion, avarice and lust.
