Question

before independence driving availabilities was the only with our work of political parties but not capturing power is the only goal of the political party

Answer 1

Before India's independence and a decade or a little more after that, joining politics meant getting oneself involved with social service. Working for the people was the prime motive and representing them in the legislative assemblies or in parliament meant speaking up for people and fighting for their cause.
Subsequently, politics in India became a route to self aggrandisement.  Today, a larger number of people join politics for making money in an unjust way and promoting their own coterie's or group's interests is their driving motive. The goal is to capture power, by fair or fowl means, and then use the levers of power for self-enrichment is the general order of the day. Rendering social service or working for the betterment of people has become the exception.
