This song first appears during the titles in the beginning of the movie. Later, it also appears time to time giving moral strength to the character played by Dharmendra. I have chosen the first version since it is the full song.
Movie: This song appears in 1974 social drama Dost (Friend) directed by Dulal Guha and produced by Premji under the banner of Suchitra. The movie starred Dharmendra, Hema Malini, Shatrughan Sinha, late Asit Sen, late Rehman, late Abhi Bhattacharya, etc.
Maanav (Dharmendra) is an orphan, brought up by the Catholic Priest Father Francis (Abhi Bhattacharya). Post his M A, Maanav returns home to Tara Devi and finds that his mentor is no more. During his train journey, this song runs in the background.
Song: The lyrics of this song were penned by Anand Bakshi and the music was composed by Lakshmikant-Pyarelal. This song appears during the titles and all through the movie in bits.
This song depicts that change and movement toward progress are important parts of life. They need to be accepted and implemented in life.
Video: Cinematography is by M Rajaram.
The video begins with a coal engine train running toward the camera. Dharmendra is sitting inside and is happy reading his guardian’s letter. He looks outside to see the natural mountainous locales. The train enters a tunnel. The song begins in the background. Dharmendra places the letter inside his inner coat pocket.
Dharmendra looks out of the window of his compartment to see the engine. The video ends with the visual of the board announcing Dharmendra’s destination – Tara Devi.
Artists: The playback singer of this song was Kishore Kumar and the onscreen performance is by Dharmendra.
Cultural Influence: This is a philosophical song depicting the journey of life. The video is watchable for the melodious and meaningful song.
