aste sthanur ivaikatra
divyam varsa-satam sthirah
vasudeve bhagavati
nanyad vedodvahan ratim
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In this way he stayed immovable in one place for one hundred years by the calculation of the demigods. After this time, he developed pure devotional attraction for Krsna, the Supreme Personality of Godhead, and remained fixed in that position.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
bahunam janmanam ante
jñanavan mam prapadyate
vasudevah sarvam iti
sa mahatma sudurlabhah
“After many births and deaths, he who is actually in knowledge surrenders unto Me, knowing Me to be the cause of all causes and all that is. Such a great soul is very rare.” (Bg. 7.19) Vasudeva, the Supreme Personality of Godhead, Krsna, is everything, and one who knows this is the greatest of all transcendentalists. It is stated in Bhagavad-gita that one realizes this after many, many births. This is also confirmed in this verse with the words divyam varsa-satam, “one hundred years according to the calculation of the demigods.” According to the calculations of the demigods, one day (twelve hours) is equal to six months on earth. A hundred years of the demigods would equal thirty-six thousand earth years. Thus King Malayadhvaja executed austerities and penances for thirty-six thousand years. After this time, he became fixed in the devotional service of the Lord. To live on earth for so many years, one has to take birth many times. This confirms the conclusion of Krsna. To come to the conclusion of Krsna consciousness and remain fixed in the realization that Krsna is everything, as well as render service unto Krsna, are characteristics of the perfectional stage. As said in Caitanya-caritamrta (Madhya 22.62), krsne bhakti kaile sarva-karma krta haya: when one comes to the conclusion that Krsna is everything by worshiping or by rendering devotional service unto Krsna, one actually becomes perfect in all respects. Not only must one come to the conclusion that Krsna is everything, but he must remain fixed in this realization. This is the highest perfection of life, and it is this perfection that King Malayadhvaja attained at the end.
