In Sanskrit, स्मृति (Smṛiti) comes from the root √स्मृ (smṛ), meaning “to remember” or “to recollect.” Its primary meaning is memory, remembrance, or that which is remembered. In ancient philosophical systems of India such as Yoga and Nyaya, smṛiti refers to a mental process in which a previously experienced object, being or event is recalled.
According to Patañjali, the proponent of Yoga philosophy;
- Perception is an experience when the object interacts with the senses.
- It leaves an impression in the mind called saṃskāra (mental imprint).
- Repeated experiences deepen the saṃskāra.
- When conditions are suitable, the saṃskāra gives rise to smṛiti (memory or recollection).
The mind acts as the interface between individual (Jiva) and the world. In a restricted way it expands from one experience to another experience. It is actually seamless without any boundaries or partitioning but in order to present the concept for better understanding, Vedānta describes the mind as having several functional aspects:
- Manas – receives and processes sensory inputs.
- Buddhi – discrimination, decision-making.
- Ahaṃkāra – sense of “I” which is the actual reference point for worldly understanding.
- Chitta – the storehouse of impressions and memories.
To enable Buddhi, whenever required, consciousness retrieves the sanskaras stored in Chitta. These retrievals or recollections arise as smṛiti. Thus citta functions somewhat like a memory repository.
Nyāya school of thought explains memory as arising from association of an object or event with previous experience. This repetition creates persisting mental imprint that is samskar. So the trigger for rise of smriti in this system is association of event ocurring in the external world with a previous experience. For example: smell sandalwood reminds you of an old memory of a temple visit during childhood
The whole process has been carefully distinguished and categorised under three consequent steps:
- Direct perception (pratyakṣa),
- Inference (Dharana),
- Memory (smṛiti).
Memory was not considered fresh knowledge but the reappearance of previously acquired knowledge.
It is also hypothesised in some schools of thoughts like ’empiricism’ that there is nothing in intellect or Buddhi that does not pass through senses.
