Purohit should live a Sattvik life, particularly from one day prior to any Karma. Be vegetarian. Wear only white, yellow or light pink clothes at the time of any Puja, and not saffron. Do not use leather goods. Wear a white cap or turban on the head and wear Angavastra while performing the rituals.

पुरोहित को चाहिए कि जिस दिन यजमान के घर में कोई कर्म है उससे पहले दिन से ही शुद्धि रखें। सात्विक भोजन करें तथा कर्म के दिन यथासंभव फलाहार करें।  किन्तु लंबे समय तक भूखे न रहें । पुरोहित कर्म के समय  श्वेत, पीत  या गुलाबी वस्त्र ही पहनें, भगवा नहीं। पुरोहित चमड़े के सामान का  उपयोग न करें। कर्म करते समय, धोती, सिर पर श्वेत टोपी या पगड़ी पहनें तथा अंगवस्त्र धारण करें।

Karma and Sanskar are based on very esoteric Darshan. This is the gift of divine Vedas and the sages, so take them seriously.

Purohit should always have the welfare of the host in their mind. You should always be showering good wishes and blessings for Yajman even if you do not get due respect from the Yajman.

You should keep acquiring and acquainting the host with the knowledge of Vedas and inspire them to walk on the right path. Make a list of worship materials keeping in mind the financial condition of host Yajman. Poor hosts may also have to work with limited Puja  materials.

To enhance knowledge continuously Purohit should connect with Vedic pundits, saints, and learned people. Read and listen to scriptures. Learn Sanskrit and master flawless chanting of Mantra. 
The scriptures also tell us that we have to move according to the country, time, and situation. There is also a provision of Aapad Dharma during the crisis.

No Purohit or Purohit associated with the Hindu Purohit Sangh will demand money, fees, etc. in lieu of performing the Karmkand. They would follow the traditional practice of  Daan-Dakshina. It is to be known that in the scriptures, collecting money for divine deeds is considered a sin. But Purohit have the right to take Daan- Dakshina. The Purohit should chant Sandhya and Gayatri Mantra so that their virtuous deeds do not get destroyed by taking Daan- Dakshina.

Always show respect to women and look at them as mothers and daughters - Matrivat Pardareshu Pardravyushu Lostvat. Do not allow anyone to insult women, abuse them, or use language with a male-dominated mind-set. For a householder, the couple complements each other. Any work is incomplete without a wife. While performing the work, make the children sit in the front row and arrangements should be made for the saints, great men and elders, they should be welcomed with wreaths, shawls or flowers, etc. Saints and elders should be invited for food in the first place followed by children and women and finally everyone else. Sick and people with disability people should get maximum attention. Please satisfy the curiosity of children about the karmkaand.

Scriptures provide that we should not create fear in the public, but awaken their conscience. Inculcate in them the spirit of devotion, Purusharth, and discipline. Awaken them to take care of their health and cleanliness, and inculcate in them a sense of service and duty. Generate respect and compassion. Duty towards seniors, women, the helpless, poor, people suffering from loneliness other creatures, and so on. Agitate the youth against dowry, and social evils and create a sense of equality in them. Inculcate the culture of responsibility. Today the whole world is suffering from environmental and water crisis, poverty and social inequality and terrorism.

Propagate Sanatan Dharma, this is the way forward.
