## Indriyamanā / 241
**Verse Meaning:** Multiply the difference between one lakh (100,000) and three hundred sixty (360) and six thousand six hundred forty (6,640) yojanas by the square root of ten. Then multiply the resulting amount by nine and divide by sixty to obtain the extent of the object of the sense of sight. || 170 ||
**Verse 170**
**Explanation:** The Sun has 184 lanes. When the Sun is in the first inner lane, it is 180 yojanas inside Jambudvipa. The diameter of Jambudvipa is one lakh yojanas. Subtracting 180 yojanas from both sides (180 x 2), i.e., 360 yojanas, we get the diameter of the inner lane (100,000 - 360 = 99,640) yojanas. Multiplying this diameter by the square root of ten gives the circumference of the inner lane, which is approximately 315,086 yojanas. It takes one Sun two nights and days, or 48 hours or 60 muhurtas, to traverse this circumference. When the Sun is in the first inner lane, the day is 18 muhurtas long, hence it is Ayodhya. Therefore, nine muhurtas after sunrise, the Sun is over the city of Ayodhya. To find the distance from the city to sunrise, we divide the circumference of the first inner lane by sixty to get the Sun's travel distance in one muhurta. Multiplying this by nine gives the distance traveled in nine muhurtas, i.e., the distance from Ayodhya to sunrise. The circumference of the first inner lane is 315,086 yojanas. Dividing this by 60 and multiplying by 2, or dividing by 20 and multiplying by 3, we get (315,086 / 20) x 3 = 472,630 yojanas. One yojana is equal to twelve hundred fifteen dhanus, one hand, two angulas, and a little more than a fourth part of a yava. The following verses are also useful in this context:
* **Verse 57:** "Eighty times the square of the difference of the faults, multiplied by many, is the eye, well-directed and knowing."
**Root:** When the Sun is in the first inner lane, it is 150 yojanas inside Jambudvipa. Subtracting 150 yojanas from both sides, we get 360 yojanas (150 x 2). Subtracting this from the diameter of Jambudvipa, which is one lakh yojanas, we are left with (100,000 - 360) = 99,640 yojanas. Squaring this, multiplying by ten, and then taking the square root, we get the circumference of the inner lane, which is 315,086 yojanas. Dividing this by sixty and multiplying by two, we get the extent of the sense of sight.
**Verse 430:** "The circumference of the first lane, multiplied by three and divided by twenty, is forty-seven thousand two hundred."
**Verse 431:** "The second is seven hundred thousand, and the third is twenty thousand."
**First Half:**
* The circumference of the first lane, multiplied by three and divided by twenty, is forty-seven thousand two hundred.
* The second is seven hundred thousand, and the third is twenty thousand.
