Narayan devoted himself to the Bhoodan movement, so Achyut Patwardhan, a distinguished comrade in arms, left politics in the middle of his life, leaving a significant intellectual vacuum in the socialist movement.The role of Nehru was one of the major issues that harmed the prospects of socialism in India.He was at the top of Congress, and he kept infusing socialist ideology into Congress's programmes, effectively taking the wind out of the socialists' sails.The term "socialist" was added to the Indian Constitution's preamble in the 42nd amendment.Landlordism has been abolished in India in order to pave the way for Socialism.To accelerate progress toward Socialism and strengthen parliamentary democracy, a comprehensive policy of social reorganization has been implemented in the form of Panchayat Raj, Co-operative Farming, and Community Development Projects.Forms of Indian socialismDemocratic SocialismCommunitarian SocialismNehruvian SocialismTherefore, Radical Socialism is not a form of Indian socialism.
