Srimad Bhagavad Gita: Spiritual Commentaries by Yogiraj Lahiri Mahasay and Swami Sriyukteshvar, English Translation

The true spiritual commentary on the Bhagavad Gita is hereby published. Other than Kriyanvitas, no one else will be capable of understanding this, the reason being that from the beginning to end, Kriya and the states of Kriya are described here. If ordinary people read this they can create opposite meanings and, only paying attention to the words and language, will create all kinds of complicated agrumentations; thus, not understanding the essense of this, they will go about with nothing but the words. But for aware and devoted Kriyavans, this is a jewel of the heart. As they progress in Kriya - in the same way will they easily be able to discern its [the work's] true significance -distilled from the Introduction of the original Bengali Edition
