Answer in Details
People come into our lives as part of our karmic journey. Encounters, relationships, and experiences are believed to be orchestrated by the divine to help us learn important lessons, work through past karma, and progress on the path toward moksha (liberation). Shiva’s grace ensures that each soul meets those who can aid in their spiritual growth, self-realization, or the fulfillment of their dharma (life’s duty).
In essence, Lord Shiva allows or "sends" people into our lives as instruments for our transformation, to help us shed attachments, learn compassion, and ultimately realize our own divine nature.
