Being a servant of the Bhagavan is our svarupam. This means applying twelve thiruman and wearing dhoti as prescribed by the scriptures. This is what they mean by being in svarupam.
Our physical appearance should be such that it conveys that we are servants of Bhagavan. If we don’t, implies that we have not understood our svarupam.
Notes:
Once everyone sported tuft, due to circumstances of the current times, many do not keep tuft.
At least wear a kaccam and apply twelve thiruman while performing Thiruaradhanam, pitru karmas, and participating in Kalakshepam.
