Radha and Krishna (Blue Dress)
Especially for the householder devotees, the path of Deity worship is strongly recommended. As far as possible, every householder, by the direction of the spiritual master, must install the Deity of Vishnu, forms like Radha-Krishna, Lakshmi-Narayaṇa or Sita-Rama especially, or any other form of the Lord, like Nrsimha, Varaha, Gaura-Nitai, Matsya, Kurma, salagrama-sila and many other forms of Vishnu, like Trivikrama, Kesava, Acyuta, Vasudeva, Narayana and Damodara, as recommended in the Vaisnava-tantras or Puranas, and one's family should worship strictly following the directions and regulations of arcana-vidhi.
Any member of the family who is above twelve years of age should be initiated by a bona fide spiritual master, and all the members of the household should be engaged in the daily service of the Lord, beginning from morning (4 a.m.) till night (10 p.m.) by performing mangala-aratrika, niranjana, arcana, puja, kirtana, srngara, bhoga-vaikali, sandhya-aratrika, patha, bhoga (at night), sayana-aratrika, etc.
Engagement in such worship of the Deity, under the direction of a bona fide spiritual master, will greatly help the householders to purify their very existence and make rapid progress in spiritual knowledge.
Simple theoretical book knowledge is not sufficient for a neophyte devotee. Book knowledge is theoretical, whereas the arcana process is practical. Spiritual knowledge must be developed by a combination of theoretical and practical knowledge, and that is the guaranteed way for attainment of spiritual perfection.
The training of devotional service for a neophyte devotee completely depends on the expert spiritual master who knows how to lead his disciple to make gradual progress towards the path back home, back to Godhead.
One should not become a pseudo spiritual master as a matter of business to meet one's family expenditures; one must be an expert spiritual master to deliver the disciple from the clutches of impending death.
