Spiritual Guidance from Indian Mythology

Without sounding too cringy: Growing up I’ve been a bit ignorant about our culture and mythology and its teachings. I was a believer in atheism and nihilism and stuff but as I’ve grown up now, I’ve realised I am not as strong and all-knowing I’ve thought of myself against realities of life. I now seek some spiritual guidance to build a philosophy behind my life. Build some principles to guide my life ( not just restricted to professional life)

I’ve been kinda inclined towards Maharabharat (read few stories here and there) but since I’ve missed the entire part of adopting a religion and brining god into our lives at an early stage, I’m finding it very difficult to incorporate this in my adult life.

I really wanna make up for what I’ve lost in terms of spiritual guidance and teachings.

1. can anyone else relate to the same?
2. How do I proceed from here?

I’m not looking for any superficial means, but really want this to be ingrained in my lifestyle 🙏🏼
