In the Selangor Malay tale of Haji Batu, a man, journeying to perform the Haj, had to cross the fearsome Pusat Tasek (Navel of the Seas), a dangerous and fiendish place (Siapa terjatuh atau tergelincir, tersuruplah ia ke dalam pusar. Tempat menanti segala mara bahaya. Tempat duduk menantinya Nenek Sepit Pentala Naga di Laut Buih Gelombang Tujuh. Kalau si lemah yang sampai, maka hilang ghaiblah ia di mulut Raja Naga yang maha bisa).
As Haji Batu’s ship went down, he clung to the Pokok Pauh Janggi in the middle of the swirl of the Pusat Tasek, and following instructions he had received in a dream, drew himself up on 7 nails that he drove into the tree. When he reached the top, he found the nest of the mythical gigantic Burong Roc (Garuda) that lived there. He waited therein and when the Roc returned, he attached himself to the bird and flew Westward on his Journey to Mecca. (see Walter William Skeat’s Malay Magic).
