## Chapter 1
**§ 184.** Now, to explain what is the cause of the attainment of knowledge, the following sutra says:
It (knowledge) is caused by the senses and the mind. ||14||
**§ 185.** The word "Indra" means "one who rules" or "one who has power." The word "Indra" also refers to the soul. Although the soul is inherently capable of knowing, it is unable to perceive objects on its own due to the obscuring karmas of knowledge. Therefore, the instrument that enables the soul to perceive objects is called the "Indriya" (sense organ), which is the "linga" (sign) of the soul. Alternatively, "linga" means "that which reveals the hidden." According to this, "Indriya" refers to the instrument that reveals the existence of the subtle soul. Just as smoke reveals the presence of fire, similarly, the sense organs like touch, etc., reveal the existence of the knower, because they cannot exist without the soul, the knower. Alternatively, "Indra" is a name-giving karma. Therefore, the sense organs are created by it. These sense organs, like touch, etc., will be discussed later.
**§ 186.** "Anindriya" (non-sense), "Manas" (mind), and "Antahkarana" (inner organ) are synonyms.
**Doubt:** How can the word "Anindriya" (non-sense) be applied to the mind, which is the "linga" (sign) of the soul, when the word "Anindriya" negates the sense?
**Solution:** The word "na" (not) here is used in the sense of "eeshad" (slightly). It means "slightly sense, slightly non-sense." Just as the word "anudara" (not having a belly) does not mean the complete absence of a belly, but rather a slightly smaller belly, similarly, we should understand it here.
**Doubt:** "Anindriya"
