Yoga is not performed/taught here. This is a holy place. You may do meditation though.
Scarfs are available at Gurudwara?
For yoga, you can go to Art of living. They have different programmes and follow up sessions on that. This is is a sikh temple and yoga wouldn't be a regular thing here.
It's the temple Sikhs go to ( Guru's Dwaar = Guru's Door= Gurudwara)
I eas not aware there any such sessions
