but rather than going there just to meet the buzrugs, the actual point of this effort is to go in jamaat and make sacrifices yourself in order to do your own tarbiyyah first, and then become the means of other peoples hidaya.
Assalamu alaykum Weekly Ijtemah for Delhites is on Thursdays, Asr to eisha (late jamaath) Introduce yourself to the masjid-waar-jamaath saathhees in the nearest masjid from your house, attend the weekly mashwarah of your halqah. You will be one or two hand shakes away from elders of Nizamuddin in few days. Inshaa Allah in a few weeks we can hear about activities in Nizamuddin from you.
Alhumdulillah I have gone Nizamuddin so many times One thing keep in ur mind it is not easy to meet buzurg of Nizamuddin because they are very very busy if you have any serious query or something which is very very important then only try to meet Buzurgs of Nizamuddin otherwise as one of SF brother said attend weekly ijtema which is on Thursday and i have seen from my eyes people in nizamuddin who come from around the world they die to meet Hazrat Maulana Saa'd Sahab BUT as i said it is not easy of busy schedule by grace of Allah this sinner got 4 times chance to meet Maualan SAA'D sahab
