A verse written by Great Sage Achyutananda Das Ji in Maalika –
“शेष कली लीला भवतु आगे बुझाई कहिबे
सर्वलो जाइफूलो कल्कि रूप धरिबे माधब।”
“Shesha kali leela bhavatu aagey bujhaai kahibey
sarvalo jaaifoolo Kalki roop dharibey Madhaba|”
At the end of Kali Yug, Lord Maha Vishnu, THE War Quoit wielding Madhava Maha Prabhu HIMSELF will take up form as Lord Kalki. Due to Lord’s illusory power (Maya) that affects all mortals, not everyone will be able to recognize HIM.
Only the devotees who accompany the Lord eternally in his divine plays and assist him in every age during establishment of Dharma (in previous ages known as Gopis or cowherds, Kapis or monkeys, and Tapi or Sages), will receive grace to recognize Lord’s incarnation.
