Many editorial changes made by Hayagriva (Professor Howard Wheeler) and comments in the 1972 edition of Bhagavad Gita are NOT in Prabhupada's original manuscript that now is in the 1983 edition of Bhagavad Gita As It Is.

The difference between the 1983 edition of Bhagavad Gita As It Is and the "incorrect 1972" edition of Bhagavad Gita As It explained here. 

Those who read only the original 1972 edition of Bhagavad Gita As It Is Ch 2 text 20 are reading the incorrect translation put there by Hayagriva dasa-

"NOR HAVING ONCE BEEN," 

These words wrongly indicate the jiva-souls have a beginning when there is no beginning or end for the jiva-souls. 

These words are not in Prabhupada's original manuscript of Bhagavad Gita As It Is. 

Those who read the 1972 edition are not understanding the jiva-souls were never "ONCE BEEN" which is really saying the jiva-souls had a beginning or were created which in incorrect. 

This is because the jiva-souls have "ALWAYS BEEN" and were NEVER  created and have no beginning or end, as corrected in the 1983 edition of Bhagavad Gita As It Is.

The jiva-souls have existed for "infinity" which means they are beginningless and endless.

Bhagavad Gita As It Is 1983 correct edition, Chapter 2 text 20-

"For the soul there is neither birth nor death at any time. He has not come into being, does not come into being, and will not come into being. He is unborn, eternal, ever-existing and primeval. He is not slain when the body is slain." (BG Ch 2 text 20)

The 1972 edition indicates the soul has a beginning when in fact it does not! People who read the 1972 Bhagavad Gita As It Is are being mislead by this-

"For the soul there is never birth nor death. "Nor, having once been", does he ever cease to be. He is unborn, eternal, ever-existing, undying and primeval. He is not slain when the body is slain." (BG Ch 2 text 20)

In English "NOR HAVING ONCE BEEN" means the soul had a beginning - This is why the 1972 edition is wrong and was changed in the 1983 edition.

Prabhupada asked Jayadvaita Swami to "clean up" the punctuation and mistakes done by Hayagriva in the 1972 edition.

In "Easy Journey to Other Planets" Hayagriva left out what he did not agree with.

Those corrections are already there in the more accurate 1983 edition of Bhagavad Gita As It Is that everyone should read.*
