First of all, there is a book written by Maharaj himself. It is called "Self Knowledge and Self Realization" (edited by Jean Dunn, published in 1963, and printed in 100 copies only).

But the underlying text we talk about is a translation of notes recorded during meetings by a disciple called Kshirsagar.

Based on the same facts that you mention, I understood that remark as the denotation of the translators, translating two different terms in Marathi to "Consciousness" and "consciousness" in English.

So to trace a possible usage of this denotation, we must inspect who were involved and especially who the translators were:

The text in the underlying book was obtained from Dinkar Keshav Kshirsagar, a close disciple of Maharaj (the one who recorded the underlying original dialogues during a series of talks in the years 1977-1979, he used to visit Maharaj twice a week during these years). The original Marathi text was approved by Maharaj himself who glanced through these notes and asked Kshirsagar to distribute them to fellow devotees.

The text was then initially translated by Dr. Mrs. Damayanti Dungaji (a disciple of Maharaj who sometimes served also as his translator during meetings, she also translated from Marathi to English a book by Siddharameshwar Maharaj (Nisargadatta's guru) under the instruction of Ranjit Maharaj (also a disciple of Siddharameshwar Maharaj)).

Later, with the guidance of Jean Dunn (a very close American disciple of Maharaj who served under his instructions as an editor of his English texts), the translation was revised by Suresh Metha (a disciple of Maharaj) with a thorough review by Kshirsagar. It is said in the acknowledgments of the book that it was also reviewed by S. K. Mullarpattan (Maharaj's primary translator).

Hence, I adopted a habit over the years when reading texts of Maharaj translated by these fellows, to be attentive to the usage of the word "consciousness" and to check if there is a consistency within the text to the usage of capital or small "c".
