Sometimes a devotee in śānta-rasa yawns, stretches his limbs, instructs on devotional service, offers respectful obeisances unto the form of the Lord, offers nice prayers to the Lord and has a desire to give direct service with his body. These are some of the common symptoms of the devotee who is situated in neutrality. One devotee, after observing the yawning of another devotee, addressed him thus: "My dear mystic, I think that within your heart there is some ecstatic devotional love which is causing you to yawn." It is sometimes found that a devotee in the śānta-rasa falls down on the ground, his hairs stand up on his body, and he trembles all over. In this way, different symptoms of ecstatic trance are exhibited automatically by such devotees.
In the Bhakti-rasāmṛta-sindhu it is said that when Lord Kṛṣṇa was blowing His conchshell known as Pāñcajanya, many great sages who were living in the caves of the mountains immediately reacted, being awakened from their trance of meditation. They immediately saw that the hairs of their bodies were standing. Sometimes devotees in śānta-rasa become stunned, peaceful, jubilant, deliberate, reflective, anxious, dexterous and argumentative. These symptoms indicate continuous ecstasy, or established emotion.
Once a great realized sage was lamenting that the Supreme Lord Kṛṣṇa was living in Dvārakā but that he was unable to take advantage of seeing Him. After thinking this, the sage immediately became stunned. He was thinking that he was simply wasting his time. In other words, the sage lamented because the Supreme Personality of Godhead was personally present but he still could not take advantage of this because of his meditation.
When a mystic is transcendental to all kinds of mental concoctions and is situated in Brahman, his state is called trance, beyond the influence of the material conception of life. In that stage, when one hears about the transcendental pastimes of the Lord, there may be shivering in the body.
