Vajrayana is a type of Buddhism that comes from Tibet, which is a country way far north of India. Vajrayana is like regular Buddhism, but it has some extra things called "tantras" which are like very special prayers and rituals.
In Vajrayana, people believe that everyone has "buddha-nature" inside them, which means they have the potential to be as wise and kind as the Buddha. In order to help people realize this, Vajrayana has special practices called "empowerments" where a teacher gives you a special blessing and teaches you how to do certain meditations and rituals.
One of the interesting things about Vajrayana is that it uses a lot of symbols and images in its practices. For example, you might see pictures of dragons, tigers, or lotuses, which represent different things.
Another thing that's different about Vajrayana is that it sometimes uses sounds and music to help people meditate. So, instead of just sitting quietly, you might chant or listen to certain sounds which are meant to help you focus your mind and feel peaceful.
Overall, Vajrayana is a very special type of Buddhism that believes in the power of special practices, symbols, and sounds to help people be more peaceful and wise.
