"Let noble thoughts come to me from all directions”

The word 'Hinduism ‘ does not appear anywhere in Hindu scriptures, The proper name for Hinduism is ‘Sanatan Dharma’ Sanatan = eternal Dharma = religion.
Hinduism cannot be described as an organized religion. It is not founded by any individual. Hinduism is God centred and therefore one can call Hinduism as founded by God, because the answer to the question ‘Who is behind the eternal principles and who makes them work?’ will have to be ‘Cosmic power, Divine power, God’
Hinduism is God centred whereas other religions are prophet centred. For this reason the whole of mankind has to abide by (or is affected by) the eternal principles. The question of acceptance or rejection of Hinduism by any individual simply does not arise, or is irrelevant. It is illogical to talk of conversion to Hinduism. It is like saying that the laws of physics (e.g.gravity) will apply to you only if you belong to an organization or organized religion.
[The ceremonies and rituals connected with Hinduism (and other religions) are designed to cultivate increased spirituality. At advanced level of spirituality, rituals and ceremonies are dispensed with]
Swami Vivekananda wrote:If you want to be religious, enter not the gate of any organised religion. They do a hundred times more evil than good, because they stop the growth of each one's individual development.... Religion is only between you and your God, and no third person must come between you. Think what these organised religions have done! What Nepoleon was more terrible than those religious persecutions? If you and I organise, we begin to hate every person . It is better not to love, if loving only means hating others. That is no love. That is hell! If loving your own people means hating everybody else, it is the quintessence of selfishness and brutality, and the effect is that it will make you brutes
"Let noble thoughts come to me from all directions"
