Conservatives vs liberal isn't really the best way to describe politics in India. While a reasonably conservative party is in power at the moment, politics in India isn't really ideologically polarized. In any era, there's one party that sets the narrative of the day, while the others try to mould themselves to fit the trend in order to avoid being left out. However, fundamentally, none of them want to upset the apple cart and challenge the core beliefs held by Indian voters, so most parties are conservatives in that sense. In fact, one of the largest opposition parties at present, the Indian National Congress, had gone to the extent of retroactively modifying the Indian constitution to nullify a progressive supreme court judgement, in order to pander to vocal islamic voters. The BJP, although they hold hardline Hindu ideals, have almost always toed the line when the supreme court has recommended progressive steps.
