Ashtadigbandhana tantra to safeguard any vastu from negative energies -Ep141 21-Jun-2020 

Sairam,
On this solar eclipse day, Gurudeva stresses the point that one should contribute spiritually and gain more spiritual power.
Eclipse effects people having more negative traits and attitudes. People who do good are least affected by any eclipse.
More than vastu, one has to clean or purify previous birth karmas in horoscope. We often ignore our karmas and instead curse or blame vastu for all bad things.
Hence one needs to safeguard or shield the atma or soul first. Earlier days, there were no CCTV system, but they had done digbandhana to the house so as to protect from negative energy attacks like thieves, unsatisfied souls, black magic effects, evil eye etc.
One can do this tantric asthadigbandhana to any vastu
Tantra as in Bhairavi tantrasara:
On Sunday, energize 8 lemons by chanting 1008 times with the mantra.
OM RIM THAM TAHA
JWAALINI JWAALINI
RIM PEETAMBARI DEVI
SARVA SHAKTI STAMBHAYA STHAMBAYA
RIM TAHAH TAHAH SWAAHA
Keep these lemons in directions - East, South, West, North, Northeast, Northwest, Southeast and Southwest.
In apartments, lemons can be kept inside the house. The tantra effect will be present till lemon is not blackened. Once it's black, redo this tantra again.
Thanks.. Sairam
