Sri Ramakrishna presents ultimate reality as Brahman, the one, undivided Reality that is both beyond all attributes and yet capable of manifesting with attributes. In its highest sense, this Reality is formless and attributeless, transcending all dualities and eluding the grasp of mind and speech. Yet the same Brahman appears as Saguna Brahman or Ishvara, the personal God who creates, preserves, and dissolves the universe and who can be approached through devotion. These are not two separate truths but two aspects of a single Reality, disclosed in different ways according to the needs and temperaments of seekers.

This ultimate Reality is characterized as Sat‑Chit‑Ananda: existence, consciousness, and bliss absolute. God is pure consciousness, the inner essence that underlies all beings and all phenomena. The universe is not outside or independent of this Reality; rather, it is a manifestation of the same divine ground, often illustrated through the image of the ocean and its waves. Individual souls and the myriad forms of the world are like waves rising and falling in the ocean of Brahman, distinct in appearance yet never separate in essence.

Ramakrishna emphasizes that this Reality is beyond the full reach of intellect and conceptual thought, and that reasoning alone cannot capture it. Genuine understanding arises through direct experience, through what may be called divine realization or darshan, made possible by intense devotion, self‑surrender, spiritual practice, and divine grace. Because God is both personal and impersonal, this realization may appear as the vision of a personal deity or as absorption in the formless absolute, each being a valid mode of encountering the same truth.

A striking feature of his teaching is the affirmation of unity amidst religious diversity. All authentic paths, whether they emphasize a personal Lord or an impersonal absolute, are seen as converging upon the same ultimate Reality. God responds to the devotee in whatever form is sincerely adored, and different religious traditions function as distinct yet convergent routes to the one summit of realization. In this way, the nature of God is disclosed as at once one and many, beyond all forms and yet present in every form that devotion and faith can meaningfully embrace.
