Hinduism
The Hindu religion has many degenerate forms thanks to the limitations of the many inferior pajeet minds in India which can't comprehend the most high god and are stuck in idol worship. However the teachings of Swami Vivekananda and certain of the advanced sages of India I readily accept. Here is what is of especial worth and emphasis in Hindu thought:
>lots of meditations based on concentration, self-observation, etc.
>all paths leading to god (the various kinds of yoga)
>each is great in his own place
>the effects of causality on higher planes (karma)
>renunciation (putting aside the not self until you find god through negation)
>affirmation (I forget if this is the exact technical term, but it's a more difficult way to find god, via seeing god in everything)
>various metaphysical concepts like Indra's Net that are good metaphors for infinity
>tremendous respect for the guests of ones home
>clear understanding of the nature of forms
>change the nature of the man
There are many books they have. Hinduism is basically the collected traditions or teachings of India going back thousands of years. There is a lot of emphasis on asceticism and on addressing each aspect of one's life so that everything can then center around god.
Some ways Hinduism goes to shit are when they are too accepting of their place in life, the pacifism gets too much out of check, they get a bit too obsessed at times about dietary laws (the muslims and the jews do this too), and some of the paths to god (which they are accepting of all) are clearly not as efficient as might be hoped for. Besides this there are Hindus that spend too much time on siddhis and other matters that then become obstacles in the path. This is warned about however in their literature. It's not really a problem with the texts at all just a problem with humans in general.
It's a pretty alright religion but it might be said there are too many guruus and too many distractions. Of interest to me concerning Christianity is they have their Bible and it holds great authority for them, what is written in the bible takes precedence over any writings that are non-canoncial. If you are a Hindu you can be lost in the mire of so many teachings for such a long time. There is in India many false preachers. We can say the same about any other religion of course too but, and correct me if I am wrong, where in the Vedas or other foundational texts of Hinduism does it ever say their works are the word of God? Where do they claim authority?
There is I should say also a very pragmatic aspect in Hinduism and also Buddhism and the oriental philosophies in general in that all of them rather than telling you the truth will with-hold it from you and instead tell you the means by which you may ascertain the truth for yourself. So there is no receiving the truth and then rejecting it. Instead there is simply the way and the clear realization that comes from a systematic procedure that gives you insight. It is expected of you that you will practice and then you will attain insight. It is also generally recommended for the average person that they have a guruu who is supposed to keep you from falling into delusions of maya, who is there to keep you on the right path. The problem is as I mentioned before; too many false teachers. How it the aspirant then to find God when he is vulnerable and ignorant and can be led astray? At least the Christians can say about their Bible that it does not lead you astray and that you can return to the Bible again and again when you do go astray and find the light there again. Similar claims are made however about the Bhagavad Gita in which it is said the book is to be read and understood in a different light 7 times, each time a new light coming to that person who reads it, until the seventh and final conception comes to them.
