If you want to light a lamp, you need four things - a container, oil, a wick and a match box. If any one of these is lacking, you cannot light the lamp. Similarly, to light the lamp of spiritual wisdom in your heart, you need – the container of detachment, wick of one-pointed concentration, matchstick of wisdom and the oil of devotion. Of these, the spirit of detachment (vairagya) is crucial. Detachment means absence of body attachment. The sense of possessiveness (mamakara) and the ego-feeling are the causes of this raga (disease). Eradicate this disease of attachment through the process of self-enquiry. When you realise the impermanence of the body and all the sensory experiences, you will naturally acquire detachment (vairagya). Discharge all your duties as an offering to God and treat your body solely as a God-given instrument for the purpose of serving others.(Divine Discourse, 9 Nov 1988).
