Interested in learning Astrology/ numerology online

Hello Everyone,

My mum is 45 years old. I have two siblings, settled in their life. My mom stays alone as my father got expired last year. I am really concerned about her as she keep on thinking about my father. I want to divert her mind. For that i am looking for kind suggestion and help from you all.

Few days back i got to know that she has started taking interest in Astrology/ numerology. I suggested her to join some course but i am not able to find any institution nearby my area.

Kindly either suggest some fruitful stuff/ work where i can divert my mum's mind or some books/ online links/ websites from where she can learn astrology/ numerology online.

Thanks in advance
