Brahmasri Musiri Dikshitar (a.k.a Musiri Mahan/Periyava) needs no introduction. All his sons are in Vedham and they all are agnihotris….I was fortunate to visit their place once. I am also aware that they have Patasala etc but did not know that they have Gosala also. Please see the appeal from Shreekaram Trust that they manage from all devotees to support their activities. Thanks to Mumbai Sriram for sharing this with me. Here is the similar posting from the past too – https://www.scribd.com/doc/250509631/brahmasri-musiri-dikshitar-s-request
To me, finding trust-worthy places is 80% of the battle while supporting good causes. This is one place we can certainly be sure that our funds will be used for intended purposes.
