One should never argue or fall out with their Acharya/Guru. They should not contest their Acharya using harsh words. They should never be insulted or slandered in any way.
Palaniyam Gurorvakyam Sarvatha Paramadarad - their command should always be respected and obeyed. One should pledge allegiance to their Guru and follow their every command. Sanak Kumar explains the consequence of contrary actions: ‘Those who slander their Guru or revered Shastras attain only the hells.’ Agastya Rishi explains the consequences befalling such a person in this lifetime: ‘Those disciples who insult their Guru become childless, friendless, without wife and without wealth. Such people never become free from misery.’ For such reasons they should worship their Guru with gifts of fruits, money, clothing, jewellery etc. Those who act in this way, enjoy the wealth of happiness.
A Guru is to be worshipped as God: Sarvadevamayo Guruha, explains Vishnu Rahasya. Therefore he is worthy of utmost respect. Guru Mahima and Guru Bhakti are a foundation on which the Hindu Sanatan Dharma stands. The Guru-Shishya tradition of India is even preserved today. Thus their greatness is unarguable and as such to fall into useless arguments with their Acharya or to speak in such a way as to defame them is undesirable. Ultimately a Guru acts for the benefit of mankind and therefore his words should be obeyed implicitly.
Lord Swaminarayan himself initiated the Dharmakul Acharya Parampara and those who disregard this great heritage in our Sampradai, disregard the greatness of Dharmakul and hence Lord Swaminarayan, for he also is a descendant of that very same Dharmakul dynasty. Without a Guru a person is lost with no identity or sense of belonging. It is a Guru that ties a Bhakta to Bhagwan and shows him the path to Moksha. Gu is darkness and ignorance; Ru is light and knowledge. Thus a Guru is one who illuminates a person to the supreme knowledge and dispells the darkness of ignorance.
