The practice of Tibetan Buddhism includes a variety of spiritual practices, including:

• Meditation: Meditation is a central practice in Tibetan Buddhism, and there are many different types of meditation that are taught in the tradition. These include calm-abiding meditation, which involves focusing the mind on a single object; insight meditation, which involves examining the nature of the mind and reality; and various visualization practices, in which practitioners visualize deities or other objects in order to cultivate certain qualities or achieve certain goals.
• Study: Tibetan Buddhists place a strong emphasis on the study of the Buddha's teachings, as well as the Tibetan translations of Indian Buddhist texts. This may involve reading and discussing the texts, as well as engaging in debate and other forms of intellectual inquiry.
• Ritual: Tibetan Buddhism includes a variety of ritual practices, including chanting, offering, and the use of prayer beads. These rituals are often used as a way to cultivate devotion and connect with the sacred.
• Cultivating compassion: Tibetan Buddhism emphasizes the importance of cultivating compassion for all beings, and this is often seen as a key aspect of the spiritual path. Practitioners may engage in various practices designed to develop compassion, such as engaging in acts of kindness and generosity, or visualizing all beings as being connected and interdependent.
• Devotion: Tibetan Buddhism places a strong emphasis on the guru-student relationship, and devotion to the guru is seen as a key aspect of the spiritual path. This may involve offering devotion to the guru through practices such as prostrations, chanting, and making offerings.

There are four main schools of Tibetan Buddhism, also known as "vehicles" or "yanas": Nyingma, Kagyu, Sakya, and Gelug. Each of these schools has its own unique practices and teachings, and they are all based on the teachings of the Buddha, as well as the Tibetan translations of Indian Buddhist texts and the teachings of Tibetan masters.

• Nyingma: The Nyingma school is the oldest of the Tibetan Buddhist schools, and it is known for its emphasis on the "old translations" of Buddhist texts that were brought to Tibet in the early period of Buddhism's introduction to the region. The Nyingma school is known for its emphasis on the practice of Dzogchen, or "great perfection," which is seen as the pinnacle of the Tibetan Buddhist path.
• Kagyu: The Kagyu school is known for its emphasis on the oral transmission of teachings from teacher to student. It is known for its emphasis on the practice of Mahamudra, which is seen as the realization of the true nature of the mind. The Kagyu school is also known for its emphasis on the role of the guru in the spiritual path.
• Sakya: The Sakya school is known for its emphasis on the study of the Buddha's teachings, as well as the practice of Vajrayana Buddhism, which involves the use of rituals, visualization practices, and other techniques to speed up the attainment of enlightenment.
• Gelug: The Gelug school is known for its emphasis on the study of the Buddha's teachings and the use of logical reasoning to understand them. It is also known for its emphasis on the practice of Lamrim, or the "stages of the path," which is a systematic approach to the spiritual path that includes both study and practice. The Gelug school is often seen as the most scholarly of the Tibetan Buddhist schools.
