The string theory of Advaita Sāṃkhya.  The corollary of the doctrine of preexistence (satkāryavāda) and the parent theory of the doctrine of time (kālavāda).  It states that the origin (mūla), the unqualified source (nirguṇa brahman), is apparently changed (vivartita) through tenfold vibration (daśaguṇa spanda).  The origin is nondimensional space.  The four dimensions (catuṣpatha) are measurable pairs of opposites (prameya dvaṃdvas).  Spirit and nature (puruṣa and prakṛti) are the nonlocal pair of opposites (alaukika dvaṃdva).  They’re united (saṃyukta) by the oversoul (īśvara), thus: {1, 3} ∪ {3, 2}.  That major triad (pradhāna traya) is the threefold source (triguṇa brahman).  It’s undifferentiated and unmanifest (nirvikalpa and avyakta).  The combined equality (saṃyukta sāmya) of its sixfold inequality (ṣaḍguṇa vaiṣamya) is the sevenfold source (saptaguṇa brahman).  The six strings (ṣaḍguṇa) being permutations, thus: 3! = 6.  And the seventh being their combination (saṃyoga).  This minor heptad (apradhāna saptaka) includes existence (sat), bliss (ānanda), consciousness (cit), the soul (jīva), mind (sattva), emotion (rajas), and physics (tamas).  They’re differentiated and manifest (savikalpa and vyakta).  Existence, bliss, and consciousness are the spiritual triad (pauruṣa traya); mind, emotion, and physics are the material triad (prākṛta traya).  They’re symbolized by the upward and downward facing triangles of the six-pointed star (ṣaṭkoṇa).  They’re united by the soul, thus: {4, 5, 6, 7} ∪ {7, 8, 9, 10}.  Furthermore, existence and physics, bliss and emotion, and consciousness and mind are the local pairs of opposites (laukika dvaṃdvas).  They’re united by the soul, thus: {4, 7} ∪ {7, 10}, {5, 7} ∪ {7, 9}, and {6, 7} ∪ {7, 8}.  These six directions (dikṣaṭka) are symbolized by the three axes of the Cartesian coordinate system and the intersection at (0, 0, 0).  Moreover, each of the seven strings (saptaguṇa) is the recursive origin (punarāvartin mūla) of a tenfold principle (daśatattva).  Each tenfold principle consists of a threefold principle (tritattva) and a sevenfold principle (saptatattva).  This yields seventy principles (saptatitattva), of which twenty-one are unmanifest (avyakta) and forty-nine are manifest (vyakta).  The former group includes the seven sheaths, the seven bodies, and the seven yogas (saptakośa, śarīra saptaka, and yoga saptaka).  The latter group includes the senses, the subtle elements, and the gross elements (indriyas, tanmātras, and mahābhūtas).  The basis of symmetry (pramā of samamiti) is numerical frequency of vibration (sāṃkhya āvṛtti of spanda).  This is best summarized by the Hermetic axiom, “As above, so below.”  The ten strings being the “above” and the seventy principles being the “below.”  From symmetry comes resonance (anunāda), which is information exchange (saṃvedana).  See Satkāryavāda.

Kālacakra:
The wheel of time.  Symbolized by the mythical snake that swallows its tail (ouroboros).  See below.
Kālavāda:
The doctrine of time.  The corollary of string theory (guṇavāda).  It states that time (kāla) is the cyclical passage (cākra saṃsāra) toward equality (sāmya).  It’s the attempt to equalize the inequality (vaiṣamya) between the spiritual and material triads (pauruṣa and prākṛta trayas).  The seven strings (saptaguṇa) are encircled (parivṛta) by the twelve spokes (dvādaśāra) of the wheel of time (kālacakra).  They’re dependent (pratītya) in that they rely on their predecessors like links in a chain.  Furthermore, they’re impermanent and successive (anitya and parampara) in that they periodically cede the focus to their successors.  Existence (sat) is twelve o’clock, bliss (ānanda) is one and eleven o’clock, and so on down to physics (tamas) at six o’clock.  Each rotation consists of four overlapping arcs (sarpiṇīs).  Each arc is delineated by a boundary line (saṃdhi).  The two vertical arcs are the descending arc and the ascending arc (avasarpiṇī and utsarpiṇī).  They’re synonymous with evolution and involution (saṃcara and pratisaṃcara).  The descending arc turns from the twelfth (dvādaśama) spoke to the sixth (ṣaṣṭha); the ascending arc turns from the sixth spoke back to the twelfth; the sixth and twelfth spokes are the boundary line.  The two horizontal arcs are the arc of rebirth and the arc of law (bhāvasarpiṇī and dhārmasarpiṇī).  They’re synonymous with suffering and happiness (duḥkha and sukha).  The arc of law turns from the third (tṛtīya) spoke to the ninth (navama); the arc of rebirth turns from the ninth spoke back to the third; the third and ninth spokes are the boundary line.  Each spoke contains endless (ananta) “wheels within wheels” (cakras within cakras).  These circular modifications (cākra vṛttis) are living aggregates of seeds (jīvana skandhas of bījas).  Modifications in the arc of law (dhārmasarpiṇī) are spiritual laws (pauruṣa dharmas); modifications in the arc of rebirth (bhāvasarpiṇī) are material things (prākṛta bhavas).  Modifications in the descending arc (avasarpiṇī) are spinning without (pravṛtti); modifications in the ascending arc (utsarpiṇī) are spinning within (nivṛtti).  Like waves (taraṃgas), modifications are mutually suppressive, supportive, generative, and interactive (anyonya abhibhava, āśraya, janana, and mithuna).  Modifications are twelvefold (dvādaśataya) and either afflicted or unafflicted (kliṣṭa or akliṣṭa).  The co-arising of suffering (samudaya of duḥkha) is afflicted modifications; the co-arising of happiness (samudaya of sukha) is unafflicted modifications.  Without restraint and without observance (ayama and aniyama), modifications become afflicted during rebirth (bhava).  Afflicted modifications are unlawful and inauspicious (adhārma and pāpa).  After the arc of rebirth, they remain accumulated (saṃcita) in their abodes (āśayas), which are mind, emotion, and physics (sattva, rajas, and tamas).  Then, after the arc of law, they’re undertaken again (punar prārabdha).  On the other hand, unafflicted modifications are lawful and auspicious (dhārma and puṇya).  They attain reabsorption (pralaya) after the arc of rebirth and become a permanent part of our nature.  See Guṇavāda.

Karmāśaya:
The abode of karma.  See Karmavāda.
Karmavāda:
The doctrine of karma, which refers to the circular consequences of our actions.  Basically, it states, “what comes around goes around” or “you reap what you sow.”  Past actions (vṛttis) originating from the afflictions (kleśas) are stored in the abode of karma (karmāśaya).  They’re to be experienced (vedanīya) again in future births (adṛṣṭa janmas).  Advaita Yoga adopts the fundamental tenets of this doctrine in its doctrine of time (kālavāda), wherein karma plays a specific part.  See Kālavāda.
Karmayoga:

Of the four causes (catuṣkāraṇa), this is the final cause, or purpose.  For example, the purpose of a clay pot is storage.  The original purpose being the unqualified source (nirguṇa brahman).  Because the purpose has no direct relationship to manifestation, it’s called the “causeless cause.”  See Kāraṇa.
Kaurava:
Relating to or belonging to the Kurus.
Kleśa:
Affliction, as opposed to remedy (bheṣaja).  The four afflictions (catuṣkleśa) are ignorance (avidyā), egotism (asmitā), attachment and aversion (rāgadveṣa), and inertia (abhiniveśa).  Ignorance is the wrong view (samyagdṛṣṭi), which is unequal vision (viṣamadṛṣṭi) of the seen (dṛśya).  It’s the field (kṣetra) of the subsequent afflictions (uttara kleśas).  Egotism is the false nature (asvarūpa) of the seen.  Attachment and aversion are the thrill (mada) of the seen.  And inertia is the binding (bandha) of the seen.  Each affliction has its own abode (āśaya).  See Āśaya.

Proof, right perception.  The three kinds (trividha) being direct perception, inference, and testimony (pratyakṣa, anumāna, and śabda).  Direct perception born of union (yogaja pratyakṣa) is primary (prādhānika).  It consists of the knower, the known, and the knowledge (jñā, jñeya, and jñāna).  They’re the agent, the object, and the action of direct perception (tripuṭī of pratyakṣa).  Direct perception born of the senses (indriyaja pratyakṣa) is secondary (aprādhānika).  It’s the apprehension of objects (adhyavasāya of viṣayas) by the senses (indriyas).  The three kinds (trividha) of inference are a priori, a posteriori, and generally seen (pūrvavat, śeṣavat, and sāmānyatodṛṣṭa).  A priori inference is drawing conclusions before observation.  A posteriori inference is drawing conclusions after observation.  Generally seen inference is drawing general conclusions from particulars.  In other words, it’s generalization.  Inference is preceded by (pūrvaka) the middle term and the major term (liṅga and liṅgin).  In the following syllogism, fire is the major term and smoke is the middle term.  “Where there’s smoke, there’s fire.  The mountain is smoky.  Therefore, the mountain is on fire.”  Testimony includes revelation, remembrance, and aphorisms (śruti, smṛti, and sūtras).  In this case, revelation refers to the Upaniṣads.  Remembrance refers to the Bhagavad Gītā.  And aphorisms refer to the Advaita Sāṃkhya Sūtras and the Advaita Yoga Sūtras.  But they only pertain to this particular tradition.  Part of spiritual maturity is studying other serious traditions and using our own discernment (viveka).
