The tattvas in Indian philosophy are elements or principles of reality. Tattvas are the basic concepts to understand the nature of absolute, the souls and the universe in Samkhya and Shaivite philosophies. Samkhya philosophy lists 25 tattvas while later Shaivite philosophies extend the number to 36. Tattvas are used to explain the structure and origin of the Universe. They are usually divided into three groups: śuddha ; śuddhaśuddha ; and aśuddha. The pure tattvas describe internal aspects of the Absolute; the pure-impure tattvas describe the soul and its limitations; while the impure tattvas include the universe and living beings that assist the existence of soul.
Overview
philosophy considers there exist only 25 tattvas - twenty four atma tattvas along with atman or soul. According to the early Shaivite philosophies, Parashiva or Parameshwara is the ultimate Reality or Parabrahman, "the one form where everything emerges. The nondualistic monism school of Shaivism, Kashmir Shaivism, describes the tattvas as Paramshiva manifests himself by a process of descent from Paramashiva to jiva, through the 36 tattvas. The vibrant creative energy of Parashiva, known as Spanda, moves him to manifest himself these 36 tattvas as a līlā or divine play. Another important sect of Shaivism, Shaiva Siddhanta, a monism-cum-dualistic school, describes the tattvas in a different perspective. Passive Parameshwara is activated itself by Suddha Maya or divine grace of him. Like that, the universe, is activated by ashudda Maya, another aspect of divine grace - Mahamaya. The interaction of Pure Maya and Impure Maya is the Pure - impure Maya where the souls attain knowledge which leads to the existence of whole universe. Mahamaya divides itself into three aspects: Śuddha Maya, Śuddha-aśuddha Maya, and Aśuddha Maya, and causes five, seven, and twenty four tattvas respectively.
Five pure tattvas
Suddha tattvas, also known as Śaiva tattvas are functioning in the absolute level which leads to the Panchakritya - Creation-Maintenance-Destruction-Concealment-Grace of almighty. Suddha tattvas are called pure because they are directly created by Shiva himself.
Śiva
Also known as Sakala tattva. One of the two aspects of the omniscient, omnipresent, conscious Absolute. In this essence, the Absolute doesn't consists of any desire, action or Knowledge related properties. It is in its pure conscious state.
Śakti
Another aspect of the Absolute. Pairing of Śiva-Śakti causes the creation of all the lower tattvas. The paired Śiva-Śakti is omniscience and consistently active. These two properties of Śiva-Śakti are known jnāna and kriyāa respectively.
Sadākhya
Also called Sadāśiva tattva or Nāda tattva. This tattva is responsible for the appearance of aham or self. This tattva is when kriyāśakti and jnānaśakti of the Absolute are in equilibrium.
Iśvara
Also known as Bindu tattva. The tattva where the fourth act of Panchakritya - delusion or concealment happens. Iśvara tattva activates the souls which are concealed by pāśa. Idam, "this is myself", i.e., the objectivation of self-awareness is caused by Iśvara tattva.
Śuddha Vidyā
Also known as Sadvidyā or Kriyā. Jnānaśakti is more initiative than kriyaśakti in Śuddhavidyā tattva. Here, "self-ness" and "this-ness" become balanced. The other three acts of Panchakritya - creation, maintenance and destruction are done below suddhavidya. These five tattvas are the Absolute which leads to the moksha of souls. Or this five tattvas can be seen as retrogradation of souls from lower state to its higher steps towards liberation.
Seven pure-impure tattvas
Pure-impure tattvas or Vidya tattvas are described as the "instruments" that assist the souls for their liberation. Soul or Atman is considered as "Purusha tattva" here, while the final manifestation of almighty is known as "Maya tattva". Maya manifests into five more tattvas known as "kanchukas" and these six tattvas adjoins the pusursha tattva and thus, produce seven vidya tattvas.
Māyā
Maya hides the divine nature of created beings as it creates the sense of separateness from the Divine and from each other.
The five ''kanchukas''
Kanchukas can be fairly translated as cloaks. They block the subject from recognising the divine nature of the Universe.
kāla - the cloak of time
vidyā - the cloak of limited knowledge
rāga - the cloak of desire
niyati - the cloak of causality
kalā - the cloak of being limited
Purusha
Purusha is the soul. It pairs with maya, the final manifestation of god along with five kancukas. These five vidya tattvas are idle in nature. So, Śiva joins with Maya and Śakti joins with three kancukas - Kāla, Niyati, Kalā. Sadasiva joins with purusha and śuddhavidya operates vidya tattva. Raga is operated by Ishvara. The activated purusha with other vidya tattvas cannot exist in universe solely. There comes the assistance of upcoming 24 asuddha tattvas.
Twenty-four impure tattvas
Impure tattvas or Atma tattvas are aspects of Universe and physical body.
Antahkarana
Consciousness within the limited purusha forms the citta made of Intellect, Ego, and Mind, known collectively as the antahkarana, or "inner organ". Buddhi is the first evolute of prakṛti. It represents the capacity of discernment. It evolves into ahamkāra after buddhi differentiates a notion of a limited individual self. That external sense of self is then experienced through the sensory mind. Ten indriyas, five tanmātras, five mahābhūtas, and the sensory mind evolve from ahamkāra as it modifies into sattvic, rajasic and tamasic modes. These 24 lowest tattvas that evolve from individual consciousness are known as the impure tattvas.
Five sense organs
The five sense organs are the most sattvic functions of manas and include:
ghrāna, i.e., the medium to experience smell
rasana, i.e., the medium to experience taste
caksus, i.e., the medium to experience colour and shape
tvāk, i.e., the medium to experience touch
śrotra, i.e., the medium to experience sound
Five motor organs
The five motor organs, each corresponding to a sense organ, represent the physical organs of action. They are the most rajasic functions of manas.
upasthā - the organ that enables procreation and sexual enjoyment
pāda - the organ that makes ambulation possible
pāni - the organ that enables grabbing and touching
vāk - the organ that makes sound/speech possible
Five subtle elements
The five subtle elements are the most tamasic functions of manas and represent the reflection of the corresponding five gross elements in the mind:
gandha
rāsa
rūpa
sparśa
śabda
Five gross elements
The five gross elements represent the final point of manifestation:
prthvi
jala
tejas
vāyu
ākāśa
While mahābhūtas are the basis for the material world, tanmātras are but limited aspects and views of it, in no way able to fully describe it. We cannot actually perceive the reality, all we can access are limited "bands" of information that form a description of reality. These bands of information are the five tanmātras. This restriction however applies only to the limited beings. For one who has gone beyond māyā, in the realm of the pure tattvas, there can be direct perception of reality, because as one's self is Ātman, so are the external objects. In such a state an enlightened being can perceive the world beyond the five senses, in a state of diversity in unity and unity in diversity.
