lord shiva will choose who can have all they desire in this world and who have to give up their attachments and desires

In the philosophy and teachings related to Lord Shiva, desires and attachments are seen as sources of bondage that keep the soul entangled in the cycle of birth and death (samsara). Lord Shiva, often called the "Destroyer of Desire" (Kameshvara), teaches that liberation (moksha) comes through transcending desires and attachments.

It is not that Lord Shiva arbitrarily chooses who can have all they desire and who must renounce. Instead, he guides all beings according to their own karma (actions) and spiritual evolution. Those who seek material desires may be granted them if it is in accordance with their karma, but ultimately, fulfillment of desires does not lead to lasting happiness or liberation.

True devotees of Lord Shiva often pray for the strength to overcome desires and attachments. The path of Shiva emphasizes vairagya (detachment) and self-realization. Through devotion, meditation, and self-discipline, a seeker gradually transcends desires and attachments, realizing the blissful state of oneness with Shiva.

As the Shiva Purana states:
_"Desires are endless and insatiable. He who conquers them through knowledge, devotion, and self-control attains Shiva."_ (Shiva Purana)

Thus, Lord Shiva teaches that letting go of desires and attachments is the way to true freedom and spiritual fulfillment.
