One of the common difficulties you encounter when travelling in a place where the language as well as writing system is different is that some places have more than one transliteration into your language, say, English for example. This is compounded by the existence of multiple names for a single site, as indeed may be seen in the case of Jaipur’s Birla Mandir. A bit of knowledge can help: for example, “mandir” stands for any place of worship, so this place is also known as the Birla Temple of Jaipur. Most temples in India are also named after the deity to whom they are dedicated, so if we take into account that this particular mandir is dedicated to the deity “Lakshmi Narayan”, it may be referred to as the Lakshmi Narayan Temple. All the other transliterations along the same vein are correct, including Laxminarayan, Lakshminarayana, etc.
Something of note to those unfamiliar with the Hindu gods is that Lakshmi Narayan refers specifically to the god Vishnu or Narayan when he is with his consort, the goddess Lakshmi. This is why all Lakshmi Narayan temples have idols of the two deities together. Hence, when you go to the Jaipur Birla Mandir, you shall see statues of the two gods beside each other: the statues of the godly couple in the Jaipur temple are particularly noteworthy, in fact, as they are better considered as a single statue alone, having been carved out of a single piece of gorgeous white marble.
There are other things to see besides the Lord Vishnu and his consort, of course. For instance, the exquisite and rather awesome sculpture of the god Ganesh or Ganesha tends to draw a great deal of interest from tourists, not least due to the richness of its garb. You also have the carvings all over the walls. Then there is the temple itself, as a whole. The structure, like most of the other Birla Mandirs (there are many other temples that go by this generic name, it being that they were all built by the famed Birla clan of India), is simply a sumptuous feat of architecture. A typical trademark of a Birla Mandir is that it is built out of the most stunning white temple and tends to be a tall building that almost always dominates every horizon where it is featured. True enough, the Jaipur mandir follows those marks, being one of the most easily spotted structures in the southern area of the city.
To get to the Jaipur Birla Mandir, you can take just about any form of transport you desire, from the autorickshaws to the buses. Everyone knows where it is: just below the Moti Dungari or Moti Dungri. It is also pretty hard to miss, since the purity of the white marble used for its construction mean that it absolutely glows during the evenings. It is definitely worth your while to go there and admire this fairly recent but still marvellously representative example of Indian religious architecture.
