I just found volumes one and two of the (five volume) Gospel of Ramakrishna, AKA the Ramakrishna Kathamrita, online. Also, it's mirrored here.

The Ramakrishna Kathamrita is one of the most important spiritual documents in the last 200 years, indeed perhaps of all time. The mystical realization of Ramakrishna influenced, and probably gave rise to, the insights of Vivekananda, Aurobindo, Gandhi, and so forth on up to, in our time, Andrew Harvey, Ken Wilber and Stuart Davis. Ramakrishna is the intellectual godfather of the New Age movement and of the Integral Movement. There are few more important books. The unabridged version is over 1000 pages, so might as well get started!
