In Parashat Lekh-Lekha, Hagar runs away from her mistress - Sara and sees angels in the wilderness. She later proclaims "that even here I saw after having (previously) seen." (Bereishit 16:13) Rashi explains that Hagar had often seen angels in Avraham and Sara's home (and for that reason she was not shocked when she saw angels later). He says that she spoke here of her excitement at seeing angels "even here in the wilderness."
Often, one is in a state or place in which there is an abundance of spiritual or religious experiences and in such a context a specific experience may not awaken that much excitement. However, when one is later in a different environment where one would not have expected such an experience it may be much more meaningful.
Similarly, one is often in a situation where one's experiences (and insights) may be traced to outside sources such as teachers and peers. When these later occur within a closed context one may derive much pleasure from that which is, in a sense, only one's own.
However, it is important to remember that just as Hagar presumably saw angels because she had lived in Avraham's home, so we must always be aware that our ability to experience in a less spiritual environment may be connected to the world of the spiritual and religious where we may have experienced in a commonplace manner. Similarly, our ability to have our own meaningful experiences (and insights) may have not grown in a vacuum but may have it's roots, even indirectly, in that which we have received from others.
