`I was low and mom (Sunanda) said this to me, 'People will hate you, rate you, shake you, and break you. How strong you stand is what makes you',` Shilpa tweeted.
Businessman Kundra, a British national, and Shilpa are co-owners of Indian Premier League (IPL) franchise Rajasthan Royals. He was questioned recently by the Delhi Police in connection with the betting scandal.
Shilpa and Kundra married in 2009 and they have a son Viaan. She says her mother's words inspired her a lot.
`Those words gave me strength immediately. Parent's unconditional love and prayers put a smile on my face. Should never take that for granted,` she tweeted.
Delhi Police have arrested 28 people in the IPL spot fixing and betting case.
