English translation included. Because the subs came from a different and shorter version, there are untranslated lines of dialog here and there. Nothing serious. There was heavy static between about the 2 to 4 minute marks. I removed what I could, making the dialog sound a bit hollow in the process. The audio is reasonably good the rest of the way.

The Encyclopedia of Indian Cinema says this about Deep Jweley Jai:

Original version of Sen’s Rajesh Khanna
psychodrama Khamoshi (1969) and one of
Suchitra Sen’s best-known performances. She
plays Radha, the hospital nurse employed by
a progressive psychiatrist (Sanyal). She is
expected to develop a personal relationship
with the male patients as part of their therapy.
The doctor diagnoses Tapash’s
(B. Choudhury) problem as an unresolved
Oedipal dilemma - the inevitable
consequence, he says, for men who are
denied a nurturing woman. He orders the
nurse to play that role, even though on an
earlier, similar occasion she fell in love with
the patient. Radha bears up to Tapash’s
violence, wears red-bordered silk saris to
impersonate his mother, sings his poetic
compositions and, in the process, falls in love
yet again. In the end, having brought about
Tapash’s mental cure, Radha has a nervous
breakdown. Suchitra Sen’s hauntingly
beautiful, often partly lit close-ups set the tone
for the film’s visual style. Hemanta
Mukherjee’s music, e.g. Ei raat tomar amar,
used a whistling chorus as a sort of leitmotif
and contributed greatly to the movie’s
success.
