Dispassion means total absence of thirst for the undue joys and celebrations of this mundane world. Dispassion means content feeling with in. dispassion means longing for ultimate one on the subject of existence either animate or inanimate.
It is very simple that sun and the night can not exist at same time so is the longing for lord and wish for mundane world can not co-exist in life.
Aversion to pleasure of senses is extremely necessary for the sprouting of divine love.
Non attachment itself is dispassion. For all spiritual purposes non attachment is most essential factor as supreme disciple of mind. Those adore it could make the spiritual path all well.
May lord bless all.
Thanks please.
