Kartik Poornima (& Guru Nanak Jayanti) Havan
This double-havan is an ancient vedic fire ritual (also homa), dedicated to the light of knowledge and awareness.
Kartika Poornima (Kartika purnima) is a Hindu, Jain and Sikh holy festival, celebrated on the Purnima (full moon) day or the fifteenth lunar day of Kartika (November–December).
It is also known as Tripuri Poornima and Tripurari Poornima. It is sometimes called Deva-Diwali or Deva-Deepawali - the festival of lights of the gods.
A ritual bath at a tirtha (a sacred water body like a lake or river) at a pilgrimage centre is prescribed on Kartik Poornima. This holy bath is known as "Kartik snana".
An holy bath at Pushkar or in the Ganges river, especially at Varanasi is deemed as most auspicious. Kartik Poornima is the most popular day for bathing in the Ganges at Varanasi.
The devotees also take a bath in the evening during moonrise and offer worship by way of six prayers such as Shiva sambuti, Satait and so forth.
Guru Nanak Gurpurab also known as Guru Nanak's Prakash Utsav, celebrates the birth of the first Sikh Guru, Guru Nanak.
This is one of the most sacred festivals in Sikhism.
Apart from Sikhs, the Nanakpanthi Hindus and other followers of Guru Nanak's philosophy also celebrate this festival.
His birth is celebrated on Kartik Poornima, i.e., the day of the full moon in the month of Kartik.
In the Gregorian Calendar, the celebration usually falls in the month of November, but its date varies from year to year, based on the traditional dates of the Indian calendar.
