Friends, you are free to download The Bhagavad Gita from this link
It is a monumental work running into many volumes totalling over 3300 pages. The Teacher, our dear Respected Swami Paramarthananda ji gave lectures on the Bhagavad Gita over several years, explained each and every verse, word by word in great detail in his inimitable style with many parables and much humour thrown in. The Student Shri P.S. Ramachandran of Coimbatore made a verbatim transcript of every single lecture, got it approved by the teacher, typeset it and presented to us as a wonderful gift in the form of a PDF book through the kind service of Shri Arsha Avinash ji and www.arshaavinash.in My koti koti pranaams to them all.
Please download and read a few pages a day, its a divine effort and gift for us all. Please share this with friends and family, do them a favour. They will thank you for the rest of their lives, I promise you.
Pranaam and best wishes in your study of the Holy Gita
