avyakta

The Sanskrit word 

अव्यक्त (avyakta) translates to "unmanifested," "invisible," "imperceptible," or "undeveloped". 

The term is a negative compound formed from:

• अ- (a-): A negative prefix, meaning "not" or "un-".
• व्यक्त (vyakta): Meaning "manifested," "expressed," "distinct," or "perceptible" (visible to the senses). 

Significance in Philosophy and Science

Avyakta is a crucial term in various schools of Indian philosophy:

• Prakṛti (Primordial Nature): In the Samkhya school of philosophy, avyakta is a synonym for Prakṛti, the primordial, unevolved material nature. It is the subtle state of existence (where the three guṇas are in perfect balance) before the universe becomes manifest.
• Brahman (The Absolute): In the Upanishads and Vedanta philosophy, avyakta can refer to the ultimate, formless, and imperceptible aspect of reality (Brahman or the Self), which is beyond sensory perception and conceptual understanding.
• Cosmology: The Bhagavad Gitā uses avyakta to describe the unmanifested state of the universe during the "night of Brahmā" (a period of dissolution), from which everything again becomes manifest at the time of creation.
• Ayurveda: In ancient Indian medicine, the term is used to describe the initial, subtle, or unclear premonitory symptoms of a disease, before it is fully manifest.

The Sanskrit word 

अव्यक्त (avyakta), meaning "unmanifested," "imperceptible," or "undeveloped," is heavily used in philosophical texts like the Upanishads, the Bhagavad Gitā, and the Purāṇas to describe the subtle nature of reality, the divine, and cosmic cycles.

Here are samples of avyakta used in various Sanskrit texts:

1. In the Bhagavad Gitā

Lord Krishna uses avyakta multiple times to describe both his own subtle, universal nature and the primal matter from which the manifest world emerges.

• Sanskrit (Chapter 8, Verse 20):

  paras tasmāt tu bhāvo 'nyo 'vyakto 'vyaktāt sanātanaḥ |
  yaḥ sa sarveṣu bhūteṣu naśyatsu na vinaśyati ||

• Translation:

  "Yet there is another nature, which is unmanifested (avyaktaḥ) and eternal, which is superior to this material unmanifested [matter]. It is supreme and is never annihilated. When all in this world is annihilated, that part remains as it is."

• Sanskrit (Chapter 12, Verse 3 - Describing the goal of Yoga):

  ye tv akṣaram anirdeśyam avyaktaṃ paryupāsate |
  sarvatra-gam acintyaṁ ca kūṭa-stham acalam dhruvam ||

• Translation:

  "But those who fully worship the unchangeable, the indefinable, the unmanifested (avyaktaṃ), the all-pervading, the unthinkable, the immovable, and the fixed—"

2. In the Katha Upaniṣad (1.3.11)

This Upaniṣad uses a hierarchical system to describe reality, positioning avyakta (Prakṛti, or primal matter) just below the ultimate Self (Puruṣa).

• Sanskrit:

  indriyebhyaḥ parā hy arthā arthebhyaś ca paraṃ manaḥ |
  manasaś ca parā buddhir buddher ātmā mahān paraḥ ||
  mahato vyaktam uttamaṃ avyaktāt puruṣaḥ paraḥ |

• Translation:

  "[...] Beyond the great Self is the unmanifested (avyaktam); beyond the unmanifested is the Supreme Being (Puruṣa)."

3. In the Śrīmad Bhāgavatam (10.3.24)

Used in prayers to the divine, referring to the imperceptible nature of God before incarnation.

• Sanskrit: rūpaṁ yat tat prahur avyaktam ādyaṁ...
• Translation: "They say that form of Yours is unperceivable/unmanifested(avyaktam), the original cause..."

apratihatā

The Sanskrit word 

अप्रतिहता (apratihatā), which is the feminine form of the adjective apratihata, translates to "uninterrupted," "unobstructed," "unimpeded," or "unchecked".

Etymology

The word is a compound term derived from:

• अ- (a-): The negative prefix, meaning "not" or "without".
• प्रतिहता (pratihatā): Meaning "stopped," "hindered," "obstructed," or "struck down".

Significance in Hindu Philosophy

Like the related term ahaitukī ("unmotivated"), the word apratihatā is primarily used in the Śrīmad Bhāgavatam to define the highest standard of pure devotional service (bhakti).

• Apratihatā Bhakti: This term refers to devotion that is "uninterrupted" or "unchecked." It describes a spiritual practice or state of consciousness that is so steady and complete that no material circumstances—whether happiness, distress, wealth, poverty, or any external obstacle—can stop the devotee from engaging in service.
• Ideal Devotion: True bhakti is described as both ahaitukī (unmotivated by self-interest) and apratihatā (continuous and unstoppable).
