In Tantric Buddhism, the generation stage (T:kye rim; S:utpatti-krama) is the first phase of meditative Buddhist sādhana associated with the 'Father Tantra' (Wylie: pha-rgyud; pa-rgyud) class of anuttara-yoga-tantras of the Sarmapa or associated with what is known as Mahayoga Tantras by the Nyingmapa. An example of a 'Father Tantra' is the Guhyasamāja Tantra. The complement of the generation/development/creation stage is the completion stage (T:dzog rim; S:saṃpanna-krama).
