Jiddu Krishnamurti was a renowned philosopher and spiritual teacher who had a profound impact on many individuals around the world. His teachings revolved around the concept of self-discovery and inner transformation, and he encouraged his followers to question their beliefs and conditioning in order to find true freedom and happiness. Some key themes in Krishnamurti's teachings include:

1. Freedom from the Known: One of the core principles of Krishnamurti's teachings is the idea of breaking free from the constraints of our conditioning and beliefs. He believed that our thoughts, beliefs, and ideologies limit our ability to see things as they truly are and prevent us from experiencing true freedom and happiness.

2. Self-Discovery: Krishnamurti emphasized the importance of self-discovery and understanding oneself. He believed that by observing ourselves without judgment and becoming aware of our thoughts, emotions, and actions, we can uncover our true nature and find inner peace.

3. The Present Moment: Another key theme in Krishnamurti's teachings is the importance of living in the present moment. He believed that the past and the future are mere illusions and that true fulfillment and happiness can only be found in the present moment.

4. Relationship and Love: Krishnamurti believed that the quality of our relationships is a reflection of our inner state. He emphasized the importance of having healthy and harmonious relationships based on love, compassion, and understanding.

5. The Observer and the Observed: According to Krishnamurti, the observer and the observed are not separate entities, but rather, they are one. He believed that by understanding the relationship between the observer (the self) and the observed (the world), we can gain insight into our own consciousness and ultimately find freedom from our conditioning.

6. Truth and Reality: Krishnamurti believed that truth and reality cannot be defined or captured by words or concepts. He encouraged his followers to look beyond their beliefs and ideologies and to directly experience the truth for themselves.

In conclusion, Jiddu Krishnamurti's teachings revolve around the themes of self-discovery, freedom from conditioning, living in the present moment, and understanding the relationship between the self and the world. He believed that by questioning our beliefs and conditioning and becoming aware of our own consciousness, we can find true freedom, happiness, and inner peace.
