The soul which is free from the defect of karma gets to the highest point of the universe, knows all and perceives all, and obtains the transcendental bliss everlasting.
You have to grow from the inside out. None can teach you, none can make you spiritual. There is no other teacher but your own soul.
When an exalted soul realises that all sentient beings are one in relation to the Supreme – that is, that all beings are the minute parts of the One – how shall he have any more delusion and what grief will come to him?
The soul that is attached to anything, however much good there may be in it, will not arrive at the liberty of Divine union. For whether it be a strong wire rope or a slender and delicate thread that holds the bird, it matters not, if it really holds it fast; for until the cord be broken, the bird cannot fly.
No work stains an individual who is pure, who is in harmony, who is master of his life, whose soul is one with the soul of all.
