Because He is the means for the goal while the refuge seeked through the mind, word and body are not truly the means, the attachments performed by mind (mAnaSika), word (vAcika) and body (kAyika) are not necessary.
Sri PBA Swami's Sarartha Deepikai:
Is attachment through the mind alone sufficient? Is it not required to seek Him through mind, word and body ("sinthaiyAlum sollAlum seykaiyAlum dEvapirAnaiyE adaintha")?
No, it is not required. Because the Lord who is seeked as the goal is also the means to reach Him. While the mind, word and body might appear on the surface as being means, they truly are not. For the goal to be reached, the necessary assent (to His protection) is sufficient.
