My lifestyle has been slowly but surely changing from a materialistic one to a more spiritual one. Lately, I like to spend most of my time contemplating God/ different scriptures, so much so that I am unable to connect with most people as I feel I do not have much in common with them. Is this situation that I am facing normal?

Swamiji says:
This perfectly normal. You don't leave the world; the world leaves you. You just feel less and less and satisfied with worldliness.
The only thing you can do for this feeling is sadhana.
