The Tibetans have followed this custom, but have made further subdivisions within these four systems. For example, within Madhyamaka, they have differentiated Svatantrika Madhyamaka from Prasangika Madhyamaka. Within Svatantrika Madhyamaka, the Gelug school has further classified Indian authors as Yogachara Svatantrika or Sautrantika Svatantrika. The various non-Gelug schools have subdivided Madhyamaka in yet other ways.
