Note: Except ISKCON, whether all of the organisational entities listed above are still (as on 23-Jan-2023) using Azhagi or not, I have no idea. As for me, personally, I feel the happiest whenever I get to know that Azhagi is used either by an individual or an organisation for spiritual/societal works. Sairam.....

Extent matters than Quantity

At the end of the day, it is not the quantity that matters but only the extent of benefit and it's long-lasting effect. For instance, apart from the fact that ISKCON uses Azhagi, please see the Divine screenshot below and also visit the following sites/pages - kaumaram.com, azhagi.com/periyavaa, azhagi.com/swami. The extent (in both effect and duration) of these sites/pages cannot be ever measured and described in words. Crores and crores must have got benefited in ways that one cannot even imagine. Sairam..... If you still feel the need (say, if you are someone apathetic towards spirituality), then you shall definitely visit sample testimonials (in Tamil) and sample testimonials (in English) and read the hearty feelings shared by some of the users therein. You may also read the next section titled "Related 'Quora' q&a and 'Youtube' videos" in this same page. Thanks.
