Chilla-nashini is a word that comes from the Urdu language and it means "to complete a spiritual journey". Think of it like going on a trip to visit a special place, like a temple or a mosque.
When someone talks about chilla-nashini, they're talking about going on a special kind of trip that's meant to help them become closer to God and feel more peaceful and happy. It's kind of like taking a very long and special journey inside yourself, where you get to disconnect from the outside world and focus on your faith and your spirituality.
People who go on a chilla-nashini are usually very dedicated to their faith. They might spend a lot of time praying, reading religious texts, meditating, and reflecting on their own lives and their connection to God. The journey can take many days or even weeks, and it's often something that people do on their own or with a small group of very close friends or family members.
Overall, chilla-nashini is a very special and personal journey, kind of like a retreat, that helps people deepen their spiritual connection and find more happiness and peace in their lives.
