The phrase "devoid of all conceptual forms" might be construed as referring to Ramakrishna's practice of "going into Samadhi": from Wiki:
Ishwar Totapuri (also Tota Puri) affectionately known as "Nangta Baba" (1780-?), born likely in Punjab, India, was a parivrajaka (wandering monk) who is said to have followed the path of the Advaita Vedanta, which is often disputed due to the meager information that exists on Totapuri.[1] By the time he arrived at Dakshineswar Temple in 1864, he was a wandering monk of the Dasnami order of Adi Shankara, and head of a monastery in the Punjab claiming the leadership of seven hundred sannyasins. He is said to have initiated Ramakrishna into Advaita Vedanta [2], as well as Anandpuri Ji from the Advait Mat tradition.[3] Totapuri taught Ramakrishna that the sole reality of the impersonal Absolute could only be realized in a state of consciousness devoid of all conceptual forms.[4]Totapuri was "a teacher of masculine strength, a sterner mien, a gnarled physique, and a virile voice". Ramakrishna affectionately addressed him as Nangta, the "Naked One", because as a renunciate he did not wear any clothing.[2]
