CHĀNDOGYA UPANISHAD · 4.15.3

एष उ एव वामनीः ।
एष हि सर्वाणि वामानि नयति ।
सर्वाणि वामानि नयति य एवं वेद ॥

eṣa u eva vāmanīḥ ।
eṣa hi sarvāṇi vāmāni nayati ।
sarvāṇi vāmāni nayati ya evaṃ veda ॥

'He is also Vâmanî, for he leads (nayati) all blessings (vâma). He leads all blessings who knows this.
