Vasubandhu, the co-founder of Yogachara Buddhism, believed in the importance of self-reflection and introspection as key practices for achieving enlightenment. He also emphasized the cultivation of compassion and the understanding of the true nature of reality.

One of the key practices recommended by Vasubandhu is mindfulness or awareness. This involves being fully present in the moment and observing one's thoughts, feelings, and sensations without judgment. By cultivating mindfulness, one can become aware of the impermanence and emptiness of all phenomena, leading to a deeper understanding of reality.

Another important practice in Yogachara Buddhism is meditation. Vasubandhu taught various meditation techniques, including mindfulness meditation, loving-kindness meditation, and analytical meditation. These practices aim to calm the mind, develop concentration, and cultivate positive emotions such as compassion and loving-kindness.

Vasubandhu also emphasized the importance of ethical conduct as a means to purify the mind and cultivate wholesome qualities. This includes following the five precepts of Buddhism, which are refraining from harming living beings, stealing, sexual misconduct, lying, and consuming intoxicants.

In addition to these practices, Vasubandhu also recommended the practice of self-reflection or self-inquiry. This involves examining one's thoughts, emotions, and actions to understand the root causes of suffering and cultivate wisdom. By understanding the true nature of the self and the world, one can overcome delusion and achieve enlightenment.

Another key technique recommended by Vasubandhu is the use of mantras and visualizations. These practices involve reciting sacred words or phrases and visualizing specific images or symbols to focus the mind and cultivate positive qualities.

Lastly, Vasubandhu emphasized the importance of studying Buddhist teachings and scriptures as a means to deepen one's understanding and practice. He believed that by studying the teachings of the Buddha and other enlightened masters, one can gain insight and wisdom that can lead to liberation from suffering.

In conclusion, Vasubandhu recommended a combination of practices and techniques in Yogachara Buddhism, including mindfulness, meditation, ethical conduct, self-reflection, mantras and visualizations, and studying Buddhist teachings. By incorporating these practices into one's daily life, one can cultivate a deeper understanding of reality and ultimately achieve enlightenment.
