in Mirror of Dharma, Venerable Geshe Kelsang Rinpoche says:
If we sincerely rely on Je Tsongkhapa and put his oral instructions into practice with strong faith, we will attain enlightenment very quickly.
The great practitioner Gyalwa Ensapa and many of his followers attained enlightenment within three years through sincerely practising the oral instructions of Je Tsongkhapa. This is magical!
Many scholars have said that the power of Je Tsongkhapa’s blessings and his skilful methods to lead practitioners to the state of enlightenment is unequalled among those of all other Buddhas.
We should rejoice in having met the doctrine of Je Tsongkhapa, and in having the opportunity to listen to and practise the oral instructions of this precious Guru who is the synthesis of all Buddhas.
