The YBh discusses numerous classic Buddhist topics dealing with the spiritual practice of both Śrāvakayāna and Mahāyāna. Some of the main topics are the eight different forms of dhyāna (meditative absorptions), the three "samādhis", different types of liberation ("vimokṣa"), meditative attainments ("samāpatti") such as "nirodhasamāpatti", the five hindrances ("nivaraṇa"), the various types of foci ("ālambana") or 'images' ("nimitta") used in meditation, the various types of meditation used as antidotes ("pratipakṣa") against the afflictions (like contemplating death, unattractiveness, impermanence, and suffering), the practice of "śamatha" through "the nine aspects of resting the mind" ("navākārā cittasthitiḥ"), the practice of insight ("vipaśyanā"), mindfulness of breathing ("ānāpānasmṛti"), how to understand the four noble truths, the thirty-seven factors of Awakening ("saptatriṃśad bodhipakṣyā dharmāḥ"), the four immeasurables ("apramāṇa"), and how to practice the six perfections ("pāramitā").
