Mahantam refers to magnanimous religious principles such as very hospitably receiving guests, even those who are uninvited and unexpected. Householders must always be magnanimous and charitable to others, being alert to curb unnecessary affection and attachment in family life. In the past, very renounced brahmana householders would collect grains that had fallen on the ground in the marketplace or those that had been left behind in the fields after harvesting. The most important item here is mayy arpitatma, or fixing the mind in Lord Krishna. Despite his material situation, anyone who constantly meditates upon the Lord can become a liberated soul. As stated in Bhakti-rasamrita-sindhu (1.2.187),
iha yasya harer dasye
karmana manasa gira
nikhilasv api avasthasu
jivan-muktah sa ucyate
"A person acting in Krishna consciousness [or, in other words, in the service of Krishna] with his body, mind, intelligence and words is a liberated person, even within the material world, although he may be engaged in many so-called material activities."
