Does numerology have an effect?

Question - Gurudev, Does numerology have an effect? There is a number which I consider lucky for me, and there are certain numbers which are not so lucky. Is this just a notion in mind or the effect actually exists?

 

Gurudev Sri Sri - That has some effect but the power of chanting ‘Om Namah Shivaye’ mantra is much more. The power of mantras can nullify the effect of any unlucky numbers, and then all the numbers will be lucky for you.
