Question: Who is considered the chief architect of the document that Hindu groups lobbied to add a cow slaughter ban to in 1966?

<P0-S0> Hindu views of homosexuality and, in general, LGBT (lesbian, gay, bisexual, and transgender) issues, are diverse and different Hindu groups have distinct views. <P0-S1>  Homosexuality is regarded as one of the possible expressions of human desire. <P0-S2>  Although some Hindu dharmic texts contain injunctions against homosexuality, a number of Hindu mythic stories have portrayed homosexual experience as natural and joyful. <P0-S3>  There are several Hindu temples which have carvings that depict both men and women engaging in homosexual sex. <P0-S4>  Same-sex relations and gender variance have been represented within Hinduism from Vedic times through to the present day, in rituals, law books, religious or so-called mythical narratives, commentaries, paintings, and sculpture. <P0-S5>  The extent to which these representations embrace or reject homosexuality has been disputed within the religion as well as outside of it. <P0-S6>  In 2009, The United Kingdom Hindu Council issued a statement that 'Hinduism does not condemn homosexuality', subsequent to the decision of the Delhi High Court to legalise homosexuality in India. <P0-S7> . <P0-S8>  The Supreme Court of India subsequently overturned the capital high court's decision in a move cheered by domestic Hindu groups in India such as the influential right-wing RSS, which concedes it should be "kept to the bedroom," does not believe it illegal but immoral as it is considered a rare condition <SEP> <P1-S0> The Constitution of India is the supreme law of India. <P1-S1>  It lays down the framework defining fundamental political principles, establishes the structure, procedures, powers and duties of government institutions and sets out fundamental rights, directive principles and the duties of citizens. <P1-S2>  It is the longest written constitution of any sovereign country in the world. <P1-S3>  B. R. Ambedkar, the chairman of the Drafting Committee, is widely considered to be its chief architect. <SEP> <P2-S0> In 1966, Hindu organisations agitated to demand a ban on the slaughter of cows in India, as enshrined in the Directive Principles of State Policy in the Constitution of India. <P2-S1>  Among others, the Shankaracharya fasted for the cause. <P2-S2>  The agitation culminated in a massive demonstration outside Sansad Bhavan in New Delhi on 7 November 1966 (as per Hindu Panchang, Vikram Samvat, Kartik Shukla Ashtami, famously known as Gopashtami among Hindus). <SEP> <P3-S0> The cow protection movement has been a religious and political movement aiming to protect the cows whose slaughter has been broadly opposed by Hindus, Buddhists, Jains and Sikhs. <P3-S1>  While the opposition to slaughter of animals including cows has extensive and ancient roots in Indian history, the term refers to modern movements dating back to the colonial era British India. <P3-S2>  The earliest such activism is traceable to Sikhs of Punjab who opposed cow slaughter in the 1860s. <P3-S3>  The movement became popular in the 1880s and thereafter, attracting the support from the Arya Samaj founder Swami Dayananda Saraswati in the late 19th-century, and from Mahatma Gandhi in early 20th-century.
