In Hinduism
Shaivism (Shaiva philosophy)
Source: Shodhganga: Iconographical representations of ŚivaSādākhya (सादाख्य).—The process of assuming the form by the transcendental god is termed as Sādākhya in Śaiva school of thought. The Tattvabhedapaṭala of Vātulāgama elaborately describes the process of Sādākhya and the Śaivotpattipaṭala of Rauravāgama describes the same process in a short manner. The Sakalaniṣkala form is known as Sādākhya, which is fivefold. Śiva with all these five is called Sadāśiva.
The five Sādākhyas are:
- Śivasādākhya,
- Amūrtasādākhya,
- Mūrtasādākhya,
- Kartṛsādākhya,
- Karmasādākhya.

Shaiva (शैव, śaiva) or Shaivism (śaivism) represents a tradition of Hinduism worshiping Shiva as the supreme being. Closely related to Shaktism, Shaiva literature includes a range of scriptures, including Tantras, while the root of this tradition may be traced back to the ancient Vedas.
Shaktism (Shakta philosophy)
Source: Google Books: Manthanabhairavatantram1) Sādākhya (सादाख्य) refers to one of the “five Siddhas” associated with the Divyaugha or Gurvogha (“current of the teachers”), as discussed in the Yogakhaṇḍa of the Manthānabhairavatantra, a vast sprawling work that belongs to a corpus of Tantric texts concerned with the worship of the goddess Kubjikā.—Three Siddhas were born from the first Siddha’s radiant energy. They were the counterparts of Brahmā, Viṣṇu and Rudra of the previous Current. After them, as in the previous Current, Five Siddhas came into being who were the counterparts of the previous ones. They entered ‘the sequence of the six parts’, that is, the Krama. Thus, along with Śrīnātha, they are the Siddhas of the sacred seats.—Sādākhya is also associated with Oḍīśa of the Divyādivya (“divine-cum-mortal current”).
According to the Kubjikāmatatantra, Sādākhya is associated with the Air principle.—The “Five Siddhas” appear as aspects of Bhairava’s five-fold form who is called Ciñciṇīnātha here. They are ‘the agents of emanation’ and govern the five gross elements. These five are the agents of emanation. In this way, the god who has five natures is established in Earth and the other (gross elements).
2) Sādākhyā (सादाख्या) or Sādākhyāgranthi refers to the “Knot of Sādākhyā (Sadāśiva)” and represents one of the “sixteen knots” (granthi), according to the Ṣaṭsāhasrasaṃhitā, an expansion of the Kubjikāmatatantra: the earliest popular and most authoritative Tantra of the Kubjikā cult.—Accordingly, “(1) The Knot called Ananta, which is HAṂSA, should be placed (on the body). It is at the middle toe of the sixteen parts (of the body).The Knot of Time is below the ankle. [...] (15) Īśvarī is in the cavity (between) the eyebrows and (16) the one called Sadāśiva (sādākhyā) is in the Sound (nāda). And Vāgbhava (AIṂ) is above the Triple Fort (trikoṭi). [...]”.
The sixteen Knots [i.e., sādākhyā-granthi] are parts of the goddess’s body. Accordingly, they are projected into the adept’s body to transform it into the Triple Fort, that is, the triangular body of the goddess replete with the energies of the sacred seats. She is both with form, consisting of the letters and mantras, and without form as the Transmental (manonmanī) energy of the god.
3) Sādākhya (सादाख्य) is used to describe Bhairava, according to the Kubjikāmatatantra: the earliest popular and most authoritative Tantra of the Kubjikā cult.—Accordingly, as Bhairava describes himself: “I am indeed the sole potter and I burn with (divine) qualities in the midst of the Skyfarers and the rest. Established in the status of a teacher, I emanate all things. I am Sādākhya of the Skyfarers, Piṅga (the Tawny One) born of the Wind. In (the element) Fire, my nature (as Ananta) is endless. I am the Lord of Grace—Anugrahīśa, born of Water. I am Śrīkaṇṭha at the culmination of completion. I am Kulīśa in the world. I grace all things. [...]”.

Shakta (शाक्त, śākta) or Shaktism (śāktism) represents a tradition of Hinduism where the Goddess (Devi) is revered and worshipped. Shakta literature includes a range of scriptures, including various Agamas and Tantras, although its roots may be traced back to the Vedas.
