I love the intricate carvings on this wonderful Mandir that is just a mile from my house.
The fluttering red-and-white flags are serving as notice that the a sovereign Deity is in residence.
On July 21, 2004 Pramukh Swami Maharaj was in Houston and blessed the spires and the flags that were to be mounted on top of the Mandir. The gold and brass leafed area of the spire represents nectar.
Wilipedia - The temple is a type of ‘Shikarbaddha’ mandir, built according to principles laid out in the Shilpa Shastras, Hindu texts prescribing standards of sacred architecture.
Within the mandir, murtis (sacred images of the deities) have been installed in different shrines. The central shrine holds the murti of Swaminarayan,
with Gunatitanand Swami to his left, together worshipped as Akshar-Purushottam Maharaj. Similarly, different shrines hold murtis of other Hindu deities
such as Radha Krishna, Shiva Parvati, Sita Ram, Hanuman, Ganapati and the lineage of BAPS gurus who are Swaminarayan’s spiritual successors.
The murtis are made from marble and are considered to be imbued with the living presence of divine beings.
Accordingly, Swaminarayan sadhus (Hindu monks) offer devotional worship to the deities throughout the day.
