This is perhaps unparalleled in the history of the Dharma.
Throughout this period his wife, Bhāmatī, served him dutifully without making any demands on his time.
The Bhāmatī has been an influential text with many sub-commentaries having appeared over the centuries.
Vācaspati Miśra (900–980 CE) was an Indian philosopher who founded one of the main Advaita Vedanta schools, the Bhāmatī school (named after his commentary on Śankara's Brahma-sūtra-bhāṣya), and whose work was an important forerunner of the Navya-Nyāya system of thought.
- Mandana Misra's (sphoṭavāda), which involves grasping the meaning of a word or sentence by perceiving a sphoṭa or single holistic sound, which is distinct from the elements (sounds or characters) that make up the word or sentence;
- the Nyāya theory which involves concatenating the memory traces (saṃskāra) of momentary components of a word or sentence when we hear the final momentary component;
- the similar Mīmāmsā theory, according to which our grasp of the meaning of a sentence lies in the memory traces created by the words; and
- the Prābhākara Mīmāmsā theory, anvitābhidhānavāda, according to which the meaning of a sentence is derived from the meanings of its words, each of which has an individual meaning in the sentence as well as having syntactic relations with the other words — no sphoṭa or memory traces are required.
After examining each of these theories, Vācaspati presents his own theory, abhihitānvayavāda, according to which understanding of the meaning of a whole sentence is reached by inferring it, in a separate act of lakṣanā or implication, from the individual meanings of the constituent words.
