Nirvikalpa enters the depth-psychology corpus through several distinct but overlapping channels, none of which permits a single authoritative definition. Zimmer’s treatment in Philosophies of India situates it structurally within the graduated stages of samādhi: nirvikalpa samādhi represents the apex of meditative absorption, preceded by and distinguished from savikalpa samādhi, with the pleasurable bliss of that penultimate stage named as the final obstacle to full attainment. Singh’s commentary on the Vijñāna Bhairava approaches the term from the Kashmir Shaiva perspective, where nirvikalpa denotes a condition of radical thought-lessness, the annihilation of vikalpa (conceptual differentiation), and is explicitly identified with undifferentiated Self-knowledge that is identical with consciousness itself. Singh further deploys nirvikalpa as a practical instruction: a chain of unbroken, object-free concentration through which the practitioner traverses the upāyas toward the śāmbhava state. Watts indexes the term without sustained analysis, positioning it within an Indian philosophical landscape defined by negation and the emptying of conceptual content. Bryant’s Yoga Sūtras commentary engages the structural cognate nirvitarka-samāpatti, absorption without conceptualization, as the Pātañjala analog. The central tension across these voices concerns whether nirvikalpa designates an epistemological category (undifferentiated knowledge), a meditative stage-state, or an ontological condition of consciousness itself — a tension that maps directly onto perennial debates between Advaita-inflected and Trika-Shaiva frameworks.
real knowledge, which is unlimited, is Self-knowledge. It is undifferentiated (nirvikalpa) and identical with consciousness. Being identical with consciousness, it is the essence of reality.
Singh identifies nirvikalpa as the defining quality of unlimited Self-knowledge, equating the thought-free, undifferentiated state directly with consciousness and with ultimate reality in Kashmir Shaivism.

The fourth and last obstacle on the way to nirvikalpa samādhi is that of the bliss of the stage just preceding it—the enjoyment of savikalpa sam
Zimmer situates nirvikalpa samādhi as the terminal stage of meditative absorption, identifying the bliss of savikalpa samādhi as the final and subtlest obstacle blocking its attainment.

you must imagine that it is all a void… Then the state of thought-lessness is revealed (nirvikalpa udayas tatah). Tatah, then, nirvikalpa udayah, the state of thoughtlessness is revealed.
Singh presents nirvikalpa as the experiential result of simultaneous voiding of subjective, objective, and cognitive fields, identifying it with the śāktopāya revelation of thought-lessness.

the process must be like a chain, without a break… When there is succession, there is the possibility [that a] foreign agency will step in the gap… only it is just a chain of nirvikalpa, one-pointed.
Singh frames nirvikalpa as a quality of unbroken, continuous concentration in which no conceptual interruption (vikalpa) can enter, describing the meditative chain as itself constituted by nirvikalpa.

the movement of prāṇa śakti is suspended… and after it is suspended… then you must see that your mind becomes absolutely unminded (nirvikalpaṃ manah kṛtvā).
Singh links the suspension of prāṇa śakti through one-pointed concentration to the production of the nirvikalpa state of mind, situating this practice within āṇavopāya.

when you go straight into that nirvikalpa moment, into that ālocana… SWAMIJI: That is śāmbhavopāya.
Singh identifies direct entry into the nirvikalpa moment with śāmbhavopāya, the highest of the three means, distinguishing it from the supported approach of śāktopāya.

Nirvikalpaḥ sukhī bhavet, so you should leave aside all doubts of purity and impurity, and you will get the blissful state of God consciousness.
Singh uses nirvikalpa to denote the state of non-discrimination that issues in blissful God consciousness, arguing that transcending the dualism of purity and impurity is itself the nirvikalpa condition.

Swamiji also defines niṣkala as ‘without any thought’, viz., nirvikalpa.
Singh explicitly equates niṣkala — the absolute, partless condition of Brahman — with nirvikalpa, grounding the term in the ontology of the unconditioned Absolute.

Zimmer’s index entry cross-references nirvikalpa within his broader treatment of Vedāntic and Yogic terminology, confirming its presence as a technical category in his philosophical synthesis.

Nirvitarka [samāpatti], ‘absorption without conceptualization,’ occurs when memory has been purged and the mind is empty, as it were, of its own [reflective] nature. Now only the object [of meditation] shines forth.
Bryant treats nirvitarka-samāpatti as the Pātañjala structural cognate of nirvikalpa samādhi, describing a cognition-free absorption in which the object alone illuminates without mental mediation.
