Mood: The mood of the video appears to be patriotic and inspirational, with a sense of optimism and hope. The theme seems to be related to national pride and development, possibly highlighting the vision of 'Modi Ji' (a reference to Indian Prime Minister Narendra Modi) for the state of Assam.

Environment: The setting of the video seems to be a symbolic or metaphorical representation of India or Assam, given the color scheme resembling the Indian flag. The environment does not appear to be a specific location but rather a stylized backdrop that evokes a sense of national identity.
