In the Carabean zone tomorrow is Narasimha Caturdasi, the appearance day of Lord Narasimha.
One should fast until dusk and chant more japamala rounds of the Hare Krishna Mantra possible.
A chapter in the Padma Purana, Uttara Khanda, describes the glories of Sri Nrsimha Caturdasi, the divine appearance day of Lord Nrsimha.
There Lord Siva narrates the following history to his wife, Parvati:
“After Lord Nrsimha had slain Hiranyakasipu, Prahlada offered prayers of heartfelt devotion and then inquired from the Lord,
“How was I able to achieve this rarest position of pure devotional service unto You?”
Lord Nrsimha replied,
“Prahlada, in your past life you were an unworthy son of a brahmana. Disregarding the Vedic scriptures, you were addicted to sinful activities. Simply by observing a complete fast from any food or water on My auspicious appearance day, Sri Nrsimha Caturdasi, you attained pure devotional service unto Me. To anyone who observes this fast, I grant eternal bliss, enjoyment, and liberation.”
