“Dreams are necessary to life.”

As Quoted in Part of Bhagat Singh's statement during his trial.
Context: The bomb was necessary to awaken England from her dreams. We dropped the bomb on the floor of the assembly chamber to register our protest on behalf of those who had no other means left to give expression to their heart-rending agony. Our sole purpose was to make the deaf hear and give the heedless a timely warning. Others have as keenly felt as we have done and from such seeming stillness of the sea of Indian humanity, a veritable storm is about to break out.

Context: A dream! What is a dream? And is not our life a dream? I will say more. Suppose that this paradise will never come to pass (that I understand), yet I shall go on preaching it. And yet how simple it is: in one day, in one hour everything could be arranged at once! The chief thing is to love others like yourself, that's the chief thing, and that's everything; nothing else is wanted — you will find out at once how to arrange it all. And yet it's an old truth which has been told and retold a billion times — but it has not formed part of our lives! The consciousness of life is higher than life, the knowledge of the laws of happiness is higher than happiness — that is what one must contend against. And I shall. If only everyone wants it, it can be arranged at once.

¿Qué es la vida? Un frenesí.
¿Qué es la vida? Una ilusión,
una sombra, una ficción,
y el mayor bien es pequeño;
que toda la vida es sueño,
y los sueños, sueños son.
Variant:
What is this life? A frenzy, an illusion,
A shadow, a delirium, a fiction.
The greatest good's but little, and this life
Is but a dream, and dreams are only dreams.
(trans. Roy Campbell)
Segismundo, Act II, l. 1195.
La vida es sueño (Life is a Dream)
