There is a mention of sethu bhanda in Brihad Parashara Hora sastra (BPHS), a popular astrological treatise done by sage Parashara, the father of Ved Vyasa.
"Chapter. 83. Effects of Curses in the Previous Birth
From verses 34-50.
"A person will be without a male issue, as a result of curse of the mother, if at birth Chandra (moon),……..
…..For release from this curse and to beget a male issue the person concerned should take bath in the sea with bridge of rocks between India and Lanka, recite one Lakh Gayatri Mantras, give in charity things, connected with evil Grahas, feed Brahmins and go round a Pipal tree 1008 times"
Samdra snaan is the propitiatory act for release from mother's curse. Even Rama did that as he had a curse from mother in the avatara of Parashurama (he killed mother).
He made use of that curse in Ramavathara which was executed through mother Kaikeyi. He could come out of that curse only after samudra snaan in Rameshwaram. After that only he could get back his wife and kingdom and could beget children. The Sethu apparently is a bund to stop the waters at Rameswaram so that mankind in the coming ages can get relief from curse. Rama's utterance of the greatness of the bund reveals this.
Lord John Sinclair Pentland (1860 – 1925) was Governor of Madras from 1912 to 1919. He visited Rameshwaram in 1914 when Sir Alexander Tottenham (1873-1946) was the District Collector of Ramanathapuram. Lord Pentland was so overwhelmed by what he saw in Rameshwaram that he wrote as follows to Lord Hardinge, the then Viceroy of India:
