The two types of demand mentioned by Gandhiji in his letter:

1. One type was of general interest.
2. Other type of demand was specific to different classes like industrialists and peasants.

Abolition of ‘Salt Tax’ was most stirring because salt was used by everyone, rich or poor and the British had monopolised its production. Gandhi wanted to unite India in its protest against the British. He believed that the unfair rule of salt production will bring all together.
