This question in this text book is based on an inaccurate premise. Hinduism, which is actually known as the Sanatana Dharma or Eternal Truth, has many uniting belief systems. These include the conviction that Truth is knowable and can be directly experienced.
Hinduism is an umbrella term for many different traditions. Each of these traditions employ different means for enlightenment and views things a bit differently. What practically all Hindu sects accept however, is the famous statement of the Rg Veda: Truth is One, the sages call it by different names.
There is therefore an underlying unity to the Hindu belief system. I don't now why this text is inaccurate on this point but I receive this question a lot. Hinduism also has a deeply shared sense of morality and ethics.
The teaching of ahimsa or non-violence is one such conviction. The belief in transmigration is another as is the belief in karma (actions and reaction), dharma (Truth) and marga (destiny). These ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
