ahaitukī

The Sanskrit word 

अहैतुकी (ahaitukī) translates to "causeless," "without reason," "unmotivated," or "disinterested". 

It is an adjective (feminine form of the neuter/masculine ahaituka) used to describe actions or states of being that are free from selfish motives or material expectations.

Etymology

The word is a compound term derived from:

• अ- (a-): A negative prefix, meaning "not" or "without".
• हेतु (hetu): Meaning "cause," "reason," or "motive". 

Significance in Hindu Philosophy

The term ahaitukī is primarily used in devotional literature to describe the highest form of pure love or devotion (bhakti).

• Ahaitukī Bhakti: This term, frequently found in the Śrīmad Bhāgavatam, refers to "unmotivated devotional service". A devotee offering ahaitukī bhakti does not seek any material gain, spiritual benefit, or even liberation in return for their service; the devotion is an inherent yearning performed without cause or expectation.
• Apratihatā: In scriptural descriptions of pure devotion, ahaitukī is often coupled with apratihatā ("uninterrupted" or "unchecked"), emphasizing that this genuine devotion cannot be stopped by any material impediments. 

For more definitions and usage examples, you can consult online Sanskrit dictionaries like sanskritdictionary.org or the Wisdom Library.

The Sanskrit word 

अहैतुकी (ahaitukī), meaning "causeless," "unmotivated," or "disinterested," is most famously used in philosophical and devotional texts (Bhakti Shastras) to describe the highest form of pure love for God.

Here are samples of ahaitukī used in various Sanskrit texts:

1. In the Śrīmad Bhāgavatam (SB 1.2.6)

This is perhaps the most famous and foundational verse that uses the term, defining pure, supreme devotion (bhakti) as unmotivated and uninterrupted.

• Sanskrit:

  sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje |
  ahaitukī apratihatā yayātmā suprasīdati ||

• Translation:

  "The supreme occupation [dharma] for all humanity is that by which men can attain to loving devotional service unto the transcendent Lord. Such devotional service must be uninterrupted and unmotivated (ahaitukī), in order to completely satisfy the self."

2. In the Caitanya-caritāmṛta (Ādi-līlā 1.4)

This text of Gauḍīya Vaiṣṇavism elaborates heavily on the concept introduced in the Bhāgavatam.

• Sanskrit:

  prema-dharma-vyākhyāna ei śāstrera sādhya |
  ahaitukī bhakti yaiche haya prema-paryāya ||

• Translation:

  "The explanation of the religious principles of love is the main objective of this scripture. It describes how unmotivated devotion (ahaitukī bhakti) is synonymous with divine love (prema)."

3. In the Bhakti-rasāmṛta-sindhu (1.1.11)

This text by Rūpa Gosvāmī provides a technical definition of pure devotional service, defining the parameters of ahaitukī.

• Sanskrit:

  anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam |
  ānukūlyena kṛṣṇānuśīlanaṁ bhaktir uttamā ||
  (Note: This verse uses synonyms for the concept of 'unmotivated'—'anyābhilāṣitā-śūnyaṁ' means 'devoid of other desires'—rather than the word ahaitukī itself, but it defines the same principle.) The commentary on this verse, however, often uses the term ahaitukī.

• Sanskrit (Commentary Context): Ahaitukī bhakti eva mukhyā.
• Translation: "Causeless/Unmotivated devotion is indeed the primary/supreme [form]."

These samples illustrate that ahaitukī is almost exclusively used to describe a very specific, high level of spiritual purity and action free from self-interest.
