It was during Kārtika that Krishna allowed Himself to be bound with ropes by His mother, Yasoda. Out of loving anger at her transcendentally naughty child, she tied him (dama) around the abdomen (udara) with ropes. Thus the month of Kārtika is also known as the month of Damodara, “He Who was bound around the abdomen”. This year, Damodara Month is from October 5 – November 3.
Srila Prabhupada discusses this at some length in Nectar of Devotion (quoting Padma Purana):
“During this month, in Vrndavana it is the regulative principle to pray daily to Lord Krishna in His Damodara form. The Damodara form refers to Krishna in His childhood when He was tied up with rope by His mother, Yasoda. Dama means ‘ropes,’ and udara means ‘the abdomen.’ So mother Yasoda, being very disturbed by naughty Krsna, bound Him round the abdomen with a rope, and thus Krishna is named Damodara.”
In the month of Kārtika (October-November); especially in Vrndavana, there is a specific program for temple worship of the Lord in His Dāmodara form. “Dāmodara” refers to Krishna’s being bound with rope by His mother, Yaśodā. It is said that just as Lord Dāmodara is very dear to His devotees, so the month known as Dāmodara or Kārtika is also very dear to them.
The execution of devotional service during Ūrja-vrata in the month of Kārtika is especially recommended to be performed at Mathurā. This system is still followed by many devotees. They go to Mathurā or Vrndavana and stay there during the month of Kārtika specifically to perform devotional services during this period.”
Prabhupada makes a point to say it is “especially recommended” to perform devotional service during Kārtika in Mathura, or Vrindavana. This is not to say that Kārtika’s benefits are exclusively available there, but devotees who are able to go make the trip if at all possible.
“Urja-vrata” refers to the acceptance of special vows during Kārtika. Devotees often take vows to increase their hearing, chanting, worship, or to observe restrictions in their eating. Making and keeping such vows during the month of Damodara guarantees compounded benefits.
Prabhupada ends Nectar of Devotion’s section on Kārtika with an interesting commentary from Padma Purana:
The Lord does not award devotional service to ordinary persons who are not serious about it. But even such unserious persons who execute devotional service according to the regulative principles during the month of Kārtika, and within the jurisdiction of Mathurā in India, are very easily awarded the Lord’s personal service.”
If even an “unserious” person can attain Krishna’s personal service, simply by “executing devotional service according to the regulative principles during the month of Kārtika”–wouldn’t it then also be a seriously good time to get serious?
During the month of Damodar, or Kārtika, Krishna always likes tulasi leaves, so it’s always a good time to offer tulasi leaves to Krishna. However, in the Hari-bhakti-vilas of Sanatan Goswami, statements: “The result one obtains by giving ten thousand cows in charity can be obtained by offering only one tulasi leaf to the Supreme Lord during the month of Kārttika.”
And those who worship Lord Hari with an offering of one hundred thousand tulasi leaves during the month of Kārtika certainly advance on the path of pure devotional service, which includes liberation, with each leaf offered. It is also recommended to offer malati (very fragrant white jasmine-like flowers) to Krishna, and here’s what Hari-bhakti-vilasa says about malati offerings during Kārttika:
It is better to offer malati flowers to Lord Kesava in the month of Kārttika than to donate gold, cows, or land to worthy recipients.
Malati flowers are pleasing to Lord Kesava (Krishna) in whatever month they are offered. In the month of Kārtika, the offering of malati flowers awards one the merit of is.
It is easy to understand the importance of the following statement, though, considering that Yamaraja is the universal superintendent in charge of meting out punishment to those who transgress karmic law:
“For a devotee who worships Lord Vishnu with offerings of malati flowers in the month of Kārtika, Yamaraja orders the removal of all his sinful reactions from the account book.”
Whatever you offer–tulasi, malati, ghee lamps, time, energy and attention takes on greater significance this month.
