Mood: The mood of this video appears to be energetic and lively, with a sense of nostalgia and emotional depth. The theme seems to revolve around music, performance, and possibly a tribute to one's mother, given the title 'Meri Maa' which translates to 'My Mother' in English.

Environment: The setting appears to be an outdoor stage or concert venue, with a metal truss structure visible behind the performer. The presence of stage lights and a microphone suggests a live performance or music video shoot. The background also features a hazy mountainous landscape, adding a scenic element to the setting.
