Its About realisation and pleasure in union with God(Tagore's song is Devotional offer to God..he is serving to God through his poem)

I touch by the edge of the far-spreading wing of my song thy feet
which I could never aspire to reach.

Drunk with the joy of singing I forget myself and call thee
friend who art my lord.

Page3- Talking about chastity and purity of Mind and it is tact to please the God..as god loves Truth and purity of Heart and Body.

Life of my life, I shall ever try to keep my body pure, knowing
that thy living touch is upon all my limbs.

I shall ever try to keep all untruths out from my thoughts,
knowing that thou art that truth which has kindled the light of
reason in my mind.

Page 4-- Talking about desertion of body so he can enjoy company of God...
( little flower refers to his body)
Pluck this little flower and take it, delay not! I fear lest it
droop and drop into the dust.

I may not find a place in thy garland, but honour it with a touch
of pain from thy hand and pluck it. I fear lest the day end
before I am aware, and the time of offering go by.

Though its colour be not deep and its smell be faint, use this
flower in thy service and pluck it while there is time.
