I am a Hindu and will go not only with my wife but family including relatives, in-laws (big deal thing actually), even the close friends of relatives who are visiting from other countries.
My wife will often chat with the other ladies, usually I am sort of like a host to friends who are from out of town. For example when a sister-in-law had a friend from Dubai, I was this gentleman's host or escort if you will to multiple temples in a single day.
Now mind you, there are formal "ceremonies" or worship called pujas - a Hindu priest before the "idols" or Murtis (forms) giving offerings, chants, and so on, little burning "lamps" are waved or taken to the assembly so the devotees can wave their palms over the flames, there is bowing, sometimes group singing and so on.
But sometimes on the way home from work I might stop at a temple - especially in the winter when it gets dark earlier, there is something magical about the open door of a temple with the lights inside that glow out into the twilight, or opening the door of the temple and entering from the outside darkness into the temple's sounds, smells, lights, (sometimes tastes and songs and dance as well) - wow! Really nice. In this example I would typically be alone if coming home from work.
Actually, this question and discission made me think, it occurs to me my wife if RARELY would go to a temple alone. The times I can think of when she went alone was when she wanted darshan and give prayer because someone was sick or she has done so to give an offering to "give me good luck at work" which is sort of funny because my luck has always been increduble and I work in IT and the computer industry but no matter how many downsizes I have seen, layoffs, et all which has been many times over the last decade especially as is the norm in IT, I never was let go, in fact only promotions, which is crazy because though I am good at what I do yet I am lazy as hell. Yet THOSE are the times my wife has gone alone to "pray for her husband and his job".
So yes, I do go alone sometimes, but my wife generally never goes alone.
I mentioned the chats my wife has with the other ladies. This happens in the "temple lobby", not right in the puja room or such. The men actually do not chat much in the temple - BUT WE CHAT A LOT OUTSIDE IN GROUPS or the classic is we chat in THE TEMPLE STORE where you might buy a prayer book, a statue or murti of a Hindu God, and such typical Hindu Temple Store type things that are found in some temples - next thing you know a nice older Hindu gentleman is handing me his business card, i.e. "if you want a nice vacation, I am a travel agent and give me a call".
Another big conversation piece is where their kid is going to school university, what each of us does for a job - IS YOUR (son, daughter, yadda) MARRIED. The women mostly ask that along with the University thing, the men talk about each others job. By the way there is no embarrassment such as one job over the next, be it a janitor or a CEO, we all share the stories and enjoy and learn from each other we men as we chat about jobs, or the "big expenses for the wedding" yadda.
I know... sounds sort of shocking to say such things such as the chatting and then arguing over who makes the best sweets the Bengalis, Americans, Gujaratis, yadda. Doesn't sound like meditation, does it?
But it is. But that is a long story for another time. There are some great emotional moments and comedic scenes you would not believe. Life is Hinduism. It includes arguing and laughing and good food. Ladies chat. Sometimes it is nice to watch the face of your wife when she chats with the other ladies. It is also Hinduism.
