This post is for the benefit of those who want to apply the art of interpreting literature as a collective dream. The eight videos embedded here represent the journey of a character, Nasir (Waheed Murad) in search of his unseen ideal. Good luck!
Stage 1: Inquiry
Nasir (which means protector, helper or supporter and hence a literal equivalent of the Greek name Alexandros, or Alexander) is in search of an unseen ideal, and is taking into account all the factors and people in his surroundings (including the working class). He is certain that Time itself will carry him forward in his journey as long as the desire is there.
Stage 2: Discovery
The ideal has manifested itself in Najma (literally meaning a celestial body, or a little star), but the protagonist is yet to know if the longing is mutual (note the wording of the first stanza).
Stage 3: Transcendence
The ideal reciprocates, and now the protagonist has found answer to the question asked in the previous stage (compare the opening lines of this song with the first stanza of the previous).
Stage 4: Freedom
The lover and the beloved are now bonded in a relationship that has a life of its own
Stage 5: Action
Deceived into believing that his ideal has turned out to be less than what he thought, the protagonist carries on the journey nevertheless: returning to the night club of the first song, he isn't "looking" any more. Thus we see his grief but also his maturity, and we may notice that self-development has taken place. This is "action" because now he is interacting with his original environment in a very different manner from how he was at the beginning. The video begins with his turning his face away from the artificial lamps of the night club and ends with him walking out of darkness into a source of light that is larger than life.
Stage 6: Expansion
Misunderstood by the one who claimed to love her, Najma asks some questions about the rules of destiny and the travails of love.
Stage 7: Creation
Since accepting a false accusation against his ideal, the protagonist has ended up with a household where unwanted guests are partying behind his back (note the invitees listed in the two stanzas of the song).
End of Stage 7: the Climax
The protagonist is now presuming that the ideal he pursued is no more (a false news about Najma's death has reached Nasir). He is at the end of his journey, contemplating suicide by falling off a cliff. His ideal saves him by returning, as if it were, from beyond this life. Note that last stanza establishes a union between the lover, the beloved and God (and the proverbial line used here, "God is the friend of those who have no friend" is actually a translation from the Persian poet Nezami Ganjavi). The video itself is full of allusions: note how the sequence from 0:40 to 0:47 alludes to the iconic tree in the movie Gone With the Wind, where the tree is the symbol of an entire society coming back to life after the devastation of a civil war. Such touches bring a meaning to this story beyond an ordinary tale about lovers, and at least some of the audience (like myself) are compelled to interpret it as an allegory about societies and nations.
