Definition - What does Kala mean?
Kala is the Sanskrit word for "time."
In the Yoga Sutras, Patanjali introduces a concept referred to as dirgha-kala, or “long time.” Dirgha-kala is the individual realization that when a new task is begun, it will not be perfected overnight. Yogis should take their time to create a solid foundation in this new undertaking—whether it be a new yoga practice, new job, an activity, a class or a relationship. No new endeavor can be perfected immediately. This principle acts as a reminder to enjoy the journey of learning something new and to intentionally build the groundwork needed to excel in the task.
Yogapedia explains Kala
In Hinduism, Kala is also known as the god of death. Kala is a manifestation of Yama, lord of the underworld and destruction. In Vedic mythology, Yama was thought to be the first mortal to die and was, therefore, made to guide all others who came after him into the underworld.
In Buddhism, especially Tibetan Buddhism, Kala is time personified. He appears as a deity in the form of Mahakala. Mahakala means "great death" in Sanskrit and is frequently depicted as a wrathful protector deity on temple walls and in religious paintings. In Hinduism, Mahakala can also be another name for the god, Shiva.
