As Shri Rukmini ji is the avatar of mahalakshmi ji, the mother of this universe and the goddess of beauty and wealth, she knows how much wealth and abundance has to be showered on her devotees. She is all- knowing, so she knew that this much wealth will be adequate for his lifetime, as Mata Rukmini and Shri Krishna were also going to bless his family and turn their small cottage into a big golden palace. Also, Maa Dwarkeshwari blessed his wife with physical beauty ( as her heart was already kind ). She also left her lotus footprints as a blessing in their palace.
Jai Maa Lakshmi swaroopini Shri Rukmini 💖👑🌸
Jai Vasudev Shri Krishna 💕🙏🏻🪷
Radhe radhe 🩷✨
