Hare Krisna Gurudev. Please accept my humble obeisance. All Glories to Srila Prabhupada.

I hope you're fine since last time you reply my letter.

                 HpS - AGTSP......  IN the DTC we explain that.  BAD    virus last three days.

In your last reply, you ask me about Krisna's book. I'm reading Srmad Bhagavatam in the morning after Mangal Aratik with my wife Carcika dd. I'm reading Caitanya Caritamrta and others small books as karma, etc during the day, daily. I'm preparing Bhakti-Yoga Introductory Course in Power Point to teach it in The Spanish Bhaktivedanta Institute too.

About of the latter, i have a question for you about how many joyanas are 1 kilometer.

Srmad Bhagavatam 5.23.9 say in the purport:

"The Vaikuṇṭha planets begin 26,200,000 yojanas(209,600,000 miles) above Satyaloka" Then 1 Yojana = 8 miles = 12,88 kilometers.

"Thus the Viṣṇu Purāṇa describes that the covering of the universe is 260,000,000 yojanas (2,080,000,000 miles) away from the sun" Then 1 Yojana = 8 miles =12,88 kilometers.

"The distance from the sun to the earth is 100,000 yojanas" Then the distance is 8.000.000 miles = 10.304.000 kilometers.

I've been looking for distance between the Sun and earth and i've found that's 149.600.000 kilometers =  11.614.906,83 miles.

Sorry if my question is speculative, but i'm trying put in place of a speculative student and i'm trying have any answers for him/her.

Thank you for all, Gurudev. 

I'm at your service.

Your servant Dandava das.

             HpS - Is big topic.  If  you look on Wikipedia it has a discussion of yojana. It seems to be a multiple of the width of a finger. Whose finger? Indra's finger? M. Pariksit's finger at the end of Dvapara yuga?   Then are yojanas they same on brahma loka as they are on the earth. Next it does not seem to be talking about the distance from the earth planet that we know to the sun, but is talking about the distance above "bhu-mandala" that the Sun keeps.  All the planets go around the earth in orbits that fall within a few degrees of inclination.  The distances in the Bhagavatam seem to developed from that perspective. Sadaputa Das explains this in detail in his books on Sacred Geometry and Structure of the Universe.   Which takes longer, to go by public transportation from NVM to Madrid airport or Madrid Airport to Barcelona?  Which is farther?                   Seems yogis could go out on sunbeams pretty easy but jumping UP to the loka ... ~planet.    Was the challenge.  So distance are calculated from that perspective.
