In plain words
Yet here we have something called special grace. When you remember God with your whole heart, with a holy feeling, with a pure heart, with selfless deeds, God takes a special part in it and keeps giving you the help you need. Yet there is a certain root to man's happiness and sorrow. In whatever birth, in whatever situation, God keeps in view the result of the good and bad that devotees have done, and goes on granting a result to match it.
Duryodhana put Draupadī through many ordeals and set out to shame her in the full assembly. Then, what help was Draupadī to find! "Keśava, Mādhava, Madhusūdana," she prayed. Who is this Keśava? Ka-a-īśa. Keśava. Ka is Brahmā. A is Viṣṇu. Īśa is Īśvara. The one who holds within Himself this form of Brahmā, Viṣṇu and Maheśvara, He alone is Keśava. O Keśava, You who are the form of the Trinity. Parāśara went on to describe this in another way. Keśava means the one who has thick locks of hair coiled in rings. Who is He? He is the very form of Brahmā, Viṣṇu and Maheśvara. She prayed. Kṛṣṇa heard. In what way am I to receive this prayer? He turned back and looked over the whole of Draupadī's history: had Draupadī done any deeds in the past that bore on this prayer? It was a Saṅkrānti day. On that day everyone chews sugarcane. On that day they had gathered round Kṛṣṇa and were enjoying themselves in delight. The gopikās, Satyabhāmā, Rukmiṇī, Jāmbavatī, Draupadī. Meaning to test them all, Kṛṣṇa, as He was peeling the sugarcane, cut His finger on purpose. To test His devotees is God's nature. But those who pass the test He goes on blessing. In the small classes, in primary school, if you want to go into 1st standard, they set a test. They set a test to see whether it is yes or no. These are not tests done out of any hatred, or for fun, or out of dislike. Out of His boundless Prema, out of compassion and grace, out of mercy, God, wishing to bless them, keeps giving them a test. Blood came from His finger. Satyabhāmā saw it. Rukmiṇī saw it. Jāmbavatī saw it. Draupadī saw it. All of them were very near and dear. The maids were all far off. Satyabhāmā saw it, called a maid and said, "Bring a cloth to bind it." Rukmiṇī herself ran off inside.
