Why does Angel Gabriel not appear in present times?

[Śrī Anil asked: In the Bible there are instances where Angel Gabriel appeared to devotees and gave direction. He appeared to Virgin Mary to tell the news of her giving birth to Jesus before her marriage. In case of father Joseph, the angel appeared in his dream to give the message to accept Mary as his wife. On another occasion, the angel appeared in the dream to Joseph asking him to escape with Mary and baby Jesus to Egypt to escape the plot of King Herod to kill baby Jesus. Swāmi, we know that You have come to give us direct guidance through excellent divine knowledge continuously. But why can we not see the appearance of Angel Gabriel in present times. Can we consider the flashes of understanding given by God in our brain in some situations to be Angel Gabriel?]

Swāmi replied: Indications regarding the birth of the Human Incarnation are always being given to the concerned people, in all times. When Kṛṣṇa was to take birth, Yogamāyā appeared to demon Kaṃsa and warned him regarding the coming of the Human Incarnation of God.
