Concept:
In the Gheranda Samhita, Dhauti is one of the important purification techniques (Shatkarma) used for cleansing the internal body systems. Dhauti is classified into different forms, among which “Antardhauti” refers to internal cleansing practices.
These practices help purify the digestive tract and remove bodily impurities, thereby preparing the practitioner for higher yogic disciplines.
Step 1: Understand the meaning of Antardhauti.
The word:
\[
\text{Antar} = \text{Internal}
\]
and
\[
\text{Dhauti} = \text{Cleansing}
\]
Thus, Antardhauti means internal purification of the body.
Step 2: Identify the types of Antardhauti mentioned in Gheranda Samhita.
According to the Gheranda Samhita, Antardhauti is of four types:
• Vatasara
• Varisara
• Vahnisara
• Bahishkrita
Therefore:
\[
\text{Number of types of Antardhauti} = 4
\]
Step 3: Analyze the given options.
Option (A): Five
Incorrect. Antardhauti is not divided into five types.
Option (B): Three
Incorrect. More than three types are mentioned.
Option (C): Four
Correct. Gheranda describes four types of Antardhauti.
Option (D): Two
Incorrect. The classification is broader than two.
Step 4: Identify the correct option.
Since Antardhauti has four types according to Gheranda, the correct answer is:
\[
\boxed{\text{Four}}
\]
