Hinduism does not have any spiritual/religious leader.
There is no one spiritual leader in Hinduism and so there is no authority on Hinduism. This is what makes it un-dogmatic (if that's a word). A priest only has jurisdiction on his 'parish' and no wider audience than that. However, there are many mythical stories of the various gods and goddesses and hindus take their examples as the ideals. But there is no compulsion to do so as you can have a living guru (spiritual guide) who you may follow. Mahatma Gandhi was a great spiritual leader in his time and although he has a place in this history books he is no longer revered as a spiritual leader today.
Current leader of Hinduism is Shankaracharya, Shree shree ravishankara Maharaja & Pramukhswami Maharaja. Also Mohan Bhagwat & Pravin Togadiya are leaders of Hinduism world wide.
A Guru or holy teacher, also know as a spiritual leader, preceptor or Holy enlightener. Occasionally, a Brahmin teaches.
Hinduism does not have any spiritual/religious head.
As far as I am aware Islam does not have a single spiritual leader, in the same way that Christianity has the Pope. Until the end of the Ottoman Empire (1918) the sultan of the Ottoman Empire was the de facto spiritual leader of Islam.
Sri Mrinalini Mata is the president and spiritual head of SRF.
The name of the current spiritual head of the Moscow Patriarchate is His Holiness Patriarch Kyril.
Yes, it is possible to convert to Hinduism. The process typically involves studying the beliefs and practices of Hinduism, seeking guidance from a Hindu spiritual leader or guru, and participating in rituals such as a formal initiation ceremony known as a "diksha." It is important to approach the conversion process with sincerity, respect, and a willingness to embrace the principles of Hinduism.
