How can I know about Swami Vivekanand

A Comprehensive Book on Hinduism [duplicate]

There is no such thing as a comprehensive book in Hinduism.

You should read a low-level introductory book that still gives a decent overview of Hinduism. Otherwise, you will have difficulty understanding Hindu scriptures. Books like "The Hindu Mind" by Bansi Pandit and "The Complete Idiot's Guide to Hinduism" by Linda Johnsen would help. Another introductory text is "A Primer of Hinduism" by DS Sharma. A good text is "Essentials of Hinduism" by Swami Bhaskarananda. A good overview of Hindu scriptures is "Windows into Infinity A Guide to Hindu Scriptures" by Barbara Powell. An advanced beginner text is "The Spiritual Heritage of India" by Swami Prabhavananda. You can also read 'Hindu Gods and Goddesses' by Swami Harshananda to learn more about the many Hindu gods and goddesses.

You can then read some of the seminal texts of Hinduism such as the Gita, the Upanishads and if you are really interested in the Brahma Sutra. You can read the Gita translated by Swami Tapasyananda. You may also read "Universal Message of the Bhagavad Gita: A Presentation of the Gita in the Light of Modern Thought and Needs" by Swami Ranganathananda. If you want to really dive deep into the subject, comments from Sankara on the Gita, the Upanishads, and the Brahma Sutra are a must. You can read Srimad Bhagavad Gita Bhasya from Sri Sankaracharya, translated by Dr. Krishna Warrier group. You can also read Brahma Sutra Bhasya from Sri Sankaracharya, translated by Swami Gambhirananda. Reading the translations of the Upanishads by Swami Nikhilananda and Swami Gambhirananda will also be helpful. You can find many seminal Hindu texts on online sites. There is a list in one of the questions here.

You can then read the 9 works of Vivekananda when you have the time. If not, then I recommend "What religion is in the words of Swami Vivekananda" edited by Swami Vidyatmananda. You can also read Patanjali's Yoga Sutra.

If you have the time, you can walk all over the Mahabharata, which is full of precious stones. You can try reading KM Ganguli's translation of the Mahabharata. You can also read the translation of Srimad Bhagavataam by Swami Tapasyananda.

By now you have acquired theoretical knowledge. If you have the time, you can read about an example of the Hindu tradition in the Ramakrishna Kathamrita (translated as "The Gospel of Sri Ramakrishna").

You can go to any Ramakrishna Vedanta center to learn more about Hindu scriptures. Information about the centers can be found on the following website: www.vedanta.org. You can get most of these books from www.vedanta.com or from Amazon.

I have given the list that I found useful. It is definitely inclined towards advaita. You must read commentaries on seminal Hindu texts by other acharyas if you are interested in other Vedantic traditions.
