Ideals and values are universal in nature. Any one individual or organization cannot appropriate them. At best, they can be reiterated over different periods of time.
Cleanliness is one such ideal that belongs to humanity and cannot be appropriated by any one person. That we should live in a clean environment and practice personal hygiene is the message of any cultured community. Indians owe a lot to Gandhiji who adhered and actively practiced this ideal. It is but natural to dedicate the idea of a clean India to Mahatma Gandhi and to actively commit ourselves towards achieving it.
