PURPORT

When a devotee feels separation from the Lord, he becomes eager to see where the Lord is, and sometimes when he feels pangs of separation, tears flow incessantly from his half-closed eyes. As stated by Sri Caitanya Mahaprabhu in His Siksastaka, yugayitam nimesena caksusa pravrsayitam. The words caksusa pravrsayitam refer to tears falling incessantly from the devotee's eyes. These symptoms, which appear in pure devotional ecstasy, were visible in the body of Prahlada Maharaja.
