The temple is said to fulfill one wish if a person vows to give up a bad habit of such a nature that may be sinful or lead to a sinful act. One such habit is  drinking alcohol or taking drugs for intoxication purpose. Another habit is habit of killing/eating animals, birds, fishes  and eggs. The temple requests visitors not to donate to the temple if they consume egg, meat, fish or consume alcohol/ drugs for intoxication purpose. The message at the donation box reads "People consuming egg, meat, fish and wine are requested not to put in their money." The temple was constructed by the contribution of the followers in terms of labour(seva) as volunteer and in terms of small amounts of money. It is claimed that the temple has been constructed by contributions from people, ninety percent of whom were below poverty line. Baba Jai Gurudev ji  Maharaj believes that mankind has five weaknesses: lust, anger, greed, attachment and egoism(vanity). He says that we are now humans again after millions of years as "lower" species. We should now get to know ourselves and our creator and return to our original home(Satloka) and to our real Lord(Satpurush), free from pain and misery. He said that the human body is made up of the five elements earth, fire, water, air and sky. He preached a specific way to meditate,  namely 'Naam-Yog Sadhana' to  achieve spiritual enlightenment. 'Naam-Yog Sadhana' is also known as 'Surat-Shabd Yoga'. 'Surat'  means soul. 'Naam/Shabd' connotes heavenly sound. Shadhana/Yoga means meditation. He  preached abiding by the rules made by the owner of this world, that is, God/Ishwar/Khuda. That means avoiding doing sins. God also owns the heaven and hell. If your deeds are good you may get some time in heaven. If a person's deeds are sinful, he/she will be sent to hell or lower forms of living beings which are also a mode or form of suffering for the soul. The time in heaven or hell or in lower order living forms will be commensurate with the degree or the amount of good or bad deeds. After it is over, the soul is again send in human form. To avoid cycles of birth and death and the sufferings, one should explore the possibility of spiritual enlightenment through Naam-Yog Sadhana/Surat-Shabd Yoga. and According to Baba Jai Gurudev ji Maharaj killing is a sin. Killing any higher order living being makes a person accumulate a sin. Plants and trees are lower order living beings .

He preaches complete abstinence from food items that may contain like egg,  meat and fish. The definition of vegetarian does not include egg, meat or fish.
