Musar para sa Mga Awit 63:9

And anything which he deems to be detrimental to this, he should flee from it as one flees from fire, similar to what is written: "my soul clings after You, Your right hand upholds me" (Ps. 63:9).

And our sages of blessed memory said "whoever scrutinizes his ways in this world merits to see the salvation of the holy One blessed be He".

The Torah exhorts us many times on the clinging [to G-d]: "to love the L-rd your G-d.. and to cling to Him" (Devarim 30:20), "to Him shall you cling" (Devarim 10:20, 13:5). And David said: "my soul clings to You" (Tehilim 63:9). All these verses speak of one matter, namely, the clinging with which a man clings to G-d, blessed be He, to such an extent that he is unable to part or move from Him.
