Though Sri Guru Raghavendra Swamy belongs to Madhwa Brahmin community, I haven’t seen a single photo of his wearing Janivaara (Yagnopavitam i.e., sacred thread). Is it because he is not reserved to one community after entering to Vrindavan or all who take Sanyasa should remove Janivar? Please enlighten me here
Sannyasis generally remove tuft (shikha), sacred thread (Yagnopavitam) and carry an "Ekadanda" (single staff) when they enter into that stage of life. Sannyasis belonging to Dvaita sampradaya also follow the same. They also take the name "Tirtha" which is one among Dashanami Sampradaya. This is the reason they do not wear Yagnopavitam or shikha.
But sannyasis belonging to Sri Vaishnava sampradaya wear both Shikha, Yagnopavitam and carry a Tridanda.
