More on understanding:
Observing or Sight
Observing has a close meaning to notice see, note, perceive, discern, remark, spot, detect, discover, distinguish, make out.
Here are some examples to use observation:
Wild life observer
Here you would be using observation in particular your vision or sight to spot how animals behave in the wild. This will help you understands animals better.
Chemistry
From chemistry you could experiment with the composition, structure, properties, and reactions of a substance. So here you can use the observation technique.
Chefs
You may use observation to learn how Chefs cook and discover different techniques and styles or draw upon their experience.
Touch
By using touch, you can learn to understand how hard or soft or whatever the feeling is of an object. For example if something is prickly you’ll learn not to touch it again because if hurts. This will help you to understand what things feel like. For example wood is hard so you can use it for a number of purposes like making a bat or building a house or using it as a weapon.
Smell
Smell helps you understand the odour of a substance and once again you’ll learn how to use or react to that substance.
Hearing
Hearing is obviously excellent of learning and communication when someone is speaking to you. But you can also use hearing to understand other things as well. For example listening to birds or whale sounds helps you understand how they communicate and learn about their behaviour.
Taste
Taste helps you understand for example if something is poisonous or not so for obvious reasons you will learn not to die or get sick from it. So, taste helps you understand flavour.
Feelings
Feelings are subjective self-contained phenomenal experiences. According to the APA Dictionary of Psychology, a feeling is "a self-contained phenomenal experience"; and feelings are "subjective, evaluative, and independent of the sensations, thoughts, or images evoking them". The term feeling is closely related to, but not the same as, emotion. Feeling may for instance refer to the conscious subjective experience of emotions. The study of subjective experiences is called phenomenology. Psychotherapy generally involves a therapist helping a client understand, articulate, and learn to effectively regulate the client's own feelings, and ultimately to take responsibility for the client's experience of the world. Feelings are sometimes held to be characteristic of embodied consciousness.
