He has done lot of miracles in Adiyen’s life to attract me towards Him. Once we are established in focus of God, I think His Mercy is liked by a devotee than His miracles.

So, in Adiyen’s opinion, miracles may be required to attract people but not for Perumal’s own benefit. However, for Yogis, His miracles may not be required to prove Himself as God.

This is Adiyen’s understanding. Please forgive mistakes if any.

Hare Krishna! Aneha koti namaskaram swami!

Swami says in Upanyasam that the lord reveals himself to devotees and hides himself for non-devotees. So in Adiyens humble opinion that lord has no need to attract anyone, but non-believers start to develop faith when they can not think of a reason per the ‘little’ brain and call it as ‘miracle’. Some believe in ‘probability’/chance when such miracle happens. Whether they believe or not, even the non-believers are serving the lord ‘indirectly’ by serving ‘maya’.

Bg 4.11 — As all surrender unto Me, I reward them accordingly. Everyone follows My path in all respects, O son of Pṛthā.

Sarvam Sri Krishnaarpanamastu!
