Once a palmist came to the house of Nanda Mahārāj, and Nanda Mahārāj asked him, "My dear sage, will you kindly check the hand of my child, Kṛṣṇa? Tell me how many years He will live and whether He will become the master of thousands of cows." Upon hearing this, the palmist began to smile, and Nanda Mahārāj asked him, "My dear sir, why are you laughing, and why are you covering your face?"
In such a laughing ecstasy of love, Kṛṣṇa or matters pertaining to Kṛṣṇa are the cause of the laughter. In such laughing devotional service, there are symptoms of jubilation, laziness, concealed feelings and similar other seemingly disturbing elements.
According to Śrīla Rūpa Gosvāmī's calculation, laughter in ecstatic love can be broken down into six divisions. These divisions, according to different degrees of smiling, are called in the Sanskrit language smita, hasita, vihasita, avahasita, apahasita, and atihasita. These six classes of smiling can be classified as major and minor. The major division includes smita, hasita and vihasita smiling, and the minor division includes avahasita, apahasita and atihasita smiling.
When one is smiling but his teeth are not visible, one can distinctly mark a definite change in the eyes and in the cheeks. This is called smita smiling. Once when Kṛṣṇa was stealing yogurt, Jaratī, the headmistress of the house, could detect His activities, and she was therefore coming very hurriedly to catch Him. At that time, Kṛṣṇa became very much afraid of Jaratī and went to His elder brother Baladeva. He said, "My dear brother, I have stolen yogurt! Just see—Jaratī is coming hurriedly to catch Me!" When Kṛṣṇa was thus seeking the shelter of Baladeva because He was being chased by Jaratī, all the great sages in the heavenly planets began to smile. This smiling is called smita smiling.
Smiling in which the teeth are slightly visible is called hasita smiling. One day Abhimanyu, the so-called husband of Rādhārāṇī, was returning home, and at that time he could not see that Kṛṣṇa was there in his house. Kṛṣṇa immediately changed His dress to look exactly like Abhimanyu and approached Abhimanyu's mother, Jaṭilā, addressing her thus: "My dear Mother, I am your real son Abhimanyu, but just see—Kṛṣṇa, dressed up like me, is coming before you!" Jaṭilā, the mother of Abhimanyu, immediately believed that Kṛṣṇa was her own son and thus became very angry at her real son who was coming home. She began to drive away her real son, who was crying, "Mother! Mother! What are you doing?" Seeing this incident, all the girl friends of Rādhārāṇī, who were present there, began to smile, and a portion of their teeth was visible. This is an instance of hasita smiling.
When the teeth are distinctly visible in a smile, that is called vihasita. One day when Kṛṣṇa was engaged in stealing butter and yogurt in the house of Jaṭilā, He assured His friends, "My dear friends, I know that this old lady is now sleeping very profoundly because she is breathing very deeply. Let us silently steal butter and yogurt without making any disturbance." But the old lady, Jaṭilā, was not sleeping; so she could not contain her smiling, and her teeth immediately became distinctly visible. This is an instance of vihasita smiling.
In a state of smiling, when the nose becomes puffed and the eyes squint, the smiling is called avahasita. Once, early in the morning when Kṛṣṇa returned home after performing His rāsa dance, Mother Yaśodā looked upon Kṛṣṇa's face and addressed Him thus: "My dear son, why do Your eyes look like they have been smeared with some oxides? Have You dressed Yourself with the blue garments of Baladeva?" When Mother Yaśodā was addressing Kṛṣṇa in that way, a girl friend who was nearby began to smile with a puffed nose and squinting eyes. This is an instance of avahasita smiling. The gopī knew that Kṛṣṇa had been enjoying the rāsa dance and that Mother Yaśodā could not detect her son's activities nor understand how He had become covered with the gopīs' makeup. Her smiling was in the avahasita feature.
When tears from the eyes are added to the smiling, and the shoulders are shaking, the smile is called apahasita. When child Kṛṣṇa was dancing in response to the singing of the old maidservant Jaratī, Nārada was astonished. The Supreme Personality of Godhead, who controls all the movements of great demigods like Brahmā and others, was now dancing to the indications of an old maidservant. Seeing this fun, Nārada also began to dance, and his shoulders trembled, and his eyes moved. Due to his smiling, his teeth also became visible, and on account of the glaring effulgence from his teeth, the clouds in the skies turned silver.
