Sri Ramanuja Munaye Namaha,
Sri Velukkudi Krishnan Swami Guruve Namaha,
Dear All BhagavAta’s,
Looks like the initial question is same as what BhagavAta is asking again.
Adiyen tried to put together the Chathur Yuga in a block format and vertical lines for the time-lines with comments as attached.
Actually, each Yuga period is short like
Kali Yuga = 360,000 years
Dwapara Yuga = 720,000 years
Thretha Yuga = 1080,000 years
Krita/Sathya Yuga = 1440,000 years
“Sandhi” means “Gap or a JUNCTION/BRIDGE” between each yughas. Here, the gap is “TIME” gap between each Yughas, and NOT a TIME OVERLAP between each Yughas.
This time gap is not accounted to each of the ACTUAL YUGHA
Like Kali Yugha Poorva Sandhi and Uttara Sandhi is each 36,000 years, but we cannot call Kali Yugha as 432,000 years. Instead Kali Yugha is 360,000 years with Time Gap “BEFORE (poorva) & AFTER (Uttara) of that YUGHA, and so as it follows for each other YUGHA’s with its own time periods.
That’s why we get confused which is start point of each YUGHA. Please see the GREEN color cells, which is the ACTUAL YUGHA’s.
So, Each actual Yughas plus ALL the Sandhi’s make up One Chatur Yugha.
1) What Swami meant is SriKrishna BhagavAn left to SriVaikuntam during the end of the ACTUAL Dwapara Yugha, and Swami NamALwar Avataram is 45 days after the ACTUAL Kali Yugha Start. Sometimes, Swami skips the Uttara Sandhi of Dwapara Yugha (72,000 years) and the Poorva Sandhi of Kali Yugha (36,000 years) intentionally, otherwise the intent of the upanyasam may get diverted to Kaala Kanakku instead of focusing on Alwar Avatara Vishayam. So when Swami delivers in Upanysams, depending up on situation, Swami says “Swami NamAlwar Avatram is 45 days after SriKrisha’s departure at the end of Dwapara Yugha, without mentioning the Uttara & Poorva sandhi of each yughas“. But in Srimadh Bhagavtam upnayasam, Swami says details of Kaala Kanakku. Also there is a Enpani where Swami says about Swami NamAlwar’s Avatram period. Adiyen couldn’t locate the Enpani audio number.
2) Veda Vyasar compiled the Srimadh Bhagavatm at the end of ACTUAL Dwapara Yugha. The Alwars Avatram in future Poorva sandhiof Klai Yugha and other Alwars avatram in the beginning of ACTUAL Kali Yugha is a Forecast by Veda Vyasar (like DIVYA DHRISTI). This is also called as Bhavishyath Vaani. Like Swami Ramanujar Avataram was also forecasted by Swami NamAlwar in Paasuram “Kaliyum Kedum Kandu Konmin…….” and Swami Ramanuajr’s 1st Archai Deity form was made by MadhuraKavi Alwar from Tamarabharani River upon Swami NamAlwar’s Kataksham during NamAlwar’s period itself.
Similar ‘Ithihaasa’ Reference for such confusion,
In Sampradhayam, Pranavam “Aum ॐ” is expanded as ஆ(for Bhagavan) + உ (for Acharyan) +ம (for BhaddhAthma).
JeevAthama (Arjuna “ம”) listened to SriKrishnan Swami’s (“ஆ”) 700 slokhas (BhagavAt Gita) DIRECTLY. Arjuna couldn’t understand overall what SriKrishnan said and got confused as well, so he never did Sharanagathy. One day, after the war was over, SriKrishna asked Arjuna, do you remember the 700 slokhas that I said in Kurushetra, he said, I don’t remember. ஆ was expecting ம to understand the slokhas meaning with its own intelligence which is covered with karmas (all of us), without Providing BLESSINGS to him to understand.
This is because there was NO Intermediate Acharya’s ( “உ” ) to elaborate the details of SriKrishnan Swami’s MIND and clear Arjuna’s confusion firmly and moreover BLESS him to understand what was said,
Intermediate Acharya’s ( “உ” ) is very important, other wise “ஆ” will say one thing and “ம” will listen one thing. It ends up in confusion. The history always repeats. Sometimes it happens in our life as well, but we intermediate BhagavAta’s are here to clear up the confusion depending up on situation.
