Srimathe Ramanujaya Namaha,
Initially in olden times, rule was set by predecessor as crossing ocean is prohibited inorder to contain the devotees in the area/Temple where they were serving, so that the services could be continued and utilized without hinderance, with the same group of orthodox people, so that they don’t need to re-teach all the Acharam lessons/train a new person, which can be done but it takes little longer time. However, if it is necessary for service or out of love towards Almighty GOD, there are exceptions allowed. Like Velukkudi Swami has crossed oceans couple of times to travel US, Australia and other countries to propagate Sampradhayam Vishayam. Srila Prapupadha in the past came to US by boat upon His Acharya Agjya to propagate Krishna consciousness.
In Sampradhayam, Vibhava Avataram and Archai is same. Swami Ramanujar in Vibhava Avataram did not cross ocean, but in Archai Avataram has crossed many oceans and residing in US, UK, Australia temples to bless devotees outside present India. Also devotees/Acharyas from India has set up Sampradhaya Mutts, Vedic centers outside India for which they travel, and when they return back to present India, they take AcharyA SriPadha theertham with a mind set that, it’s all for BhagavAt/BhagavAta Kankaryam. Definitely during travel, following the regular Acharam is difficult, but that is not the main restriction, since travelling within India from south to north Yatra itself need some Acharam to be comprised. So it’s not a big deal, if you like travelling and have some money, for service and or to visit some temples inside or outside India for satisfaction, the world is not a limit.
“The World is like a Book, those who doesn’t travel, read only one page of the book”, like நடுவில கொஞ்சம் பக்கத்தை காணோம்…..😊
