Dear all, let me outline the kubera sadhana perfection.
With dhyana and vruta, if an aspirant chants this mantra for 100,000 times, the do a homa of 10,000 number with thila and then do the pooja. The perfection will be blessed on the person.
If the mantra is chanted 10,000 times in a temple of lord shiva, one will get vast riches and wealth.
If the mantra is chanted sitting in the shade of kuvala tree for 100,000 times, he/she will be bestowed with unmeasurable money.
