Come directly to Kashmere Gate via Yellow Line... deboard there and use Red Line to reach Pratap Nagar. Use Railway Station exit gates and either use Battery Car, Rickshaw, or Auto to reach DEE. You can deboard also at Shastri Nagar use Gate no 2-3 to exit and same way use either Battery or Rickshaw.
PS: Do not go via Blue Line you will reach else where...ЁЯШВЁЯШВЁЯШВЁЯШВ
