I am looking for the beeja mantra for kuber with reference. Are there any combined lakshi kuber mantra also. Please help Thanks
I do not know Kuber beejmantra. But I know the mantra of Devi Lakshmi which made Kuber rich, Ravna able to build his golden Lanka.
The mantra is described in Devi Bhagvat.
Om Srim Hrim Klim Aem Kamalvasinyaiye Swaha
ओम श्रीं ह्रीं क्लीं ऐं कमलवासिन्यै स्वाहा |
Hope it helped.
