The Initiation: Mala Dharanam
The ritual: usually begins on the 1st of Vrischikam, when the devotee wears the Tulsi or Rudraksha mala with the locket of Lord Ayyappa.
The guru: the mala is traditionally received from a Guruswami, often understood as an experienced pilgrim who has completed the yatra many times.
The vow: after receiving the mala, the devotee renounces worldly indulgence and lives with the identity and discipline of a "Swami."
