The original text of Bhagavad Gita, all the 700 shlokas verses in Sanskrit is available at a very subsidized price ranging from $.10 to $1 from Gita press, Gorakhpur, India yet, there are no takers. Why?
Everything contained in Bhagavad Gita and other sacred texts of Hinduism cannot be understood literally, they demand our indulgence in contemplation (chintan) to reach the hidden underlying meaning.
Gita press has many publications in Sanskrit, Hindi and even English. They have presence all over India in the main cities. They also have online presence. If possible one should go through all the publications and choose what fits our appetite, our pattern of thinking.
Many other publications are available in open market at almost 10 times the price. The commentaries on Bhagavad Gita and also Upanishads (independent spiritual treatises) available with Gita press both in Hindi and English are par excellence.
Gita press virtually a storehouse of knowledge is serving the mankind at its level best.
