I haven't got much relation to it either because I was born and raised in Britain.
There's nothing wrong with them. In fact, they are deserving of respect from a Satanic perspective (India). However, no matter how much of their culture I consume it always feel's so "foreign" to me, as though I've never lived there in any past incarnation's and don't have any inherent connection to this land.
For example, I had a very strong affinity with the Greek and Nordic God's, despite when I was a christian, but a feeling of weirdness and almost repulsion to the Hindu iconography.
I don't find even their highest forms of art the least bit appealing. I dislike the clothes, music, art, everything about it.
To complicate matter's, I don't "look" Indian so people never think I'm from there, which add's another layer of feeling disconected from "my people".
There's many other similar contributing factor's, but I think I got the point across.
I'm also very Jupiter/Sagittarius/9th House heavy.
What can I do to begin to love my culture? From a magick based perspective, since I don't think a mental change could fight against the sheer energy my soul has oriented towards foreign matter's.
A Sagittarian emphasis, depending on exact placements, can result in an element of travel that may result in a looser connection to one's current surroundings. However, that may not be the same as feeling disconnected. Beyond this, it is possible for your past as a Zevist to create alienated feelings, especially if this resulted in trauma or other negative karma in a past life. On top of all of this, simply being raised differently can lead to less of a bond with another culture.
Berkano pertains to family and emotions, Othal pertains to ancestry in a broad sense, and Wunjo pertains to joy (which involves community-based happiness and harmony). All of these present different options you can use. Wunjo is probably the best all-purpose rune here. Astarte's Ritual would also be relevant and useful.
In my opinion, the priority would be reducing personal feelings of alienation and unhappiness with those around you. Although related, you don't necessarily need a deep understanding or connection; Wunjo would work on all levels necessary to create happiness, whereas something like Berkano would be more restricted to nurturing and emotions.
Now, my question would be if you are trying to connect with the culture of India, or with British Indians, as these are two different cultures. If you are a British Indian and do not have any future plans to travel to, or integrate with India itself, it may not make sense to invest a lot of time beyond creating personal comfort with your existing situation.
