Spiritual life is a process to conquer death. If you are practising spiritual life but still fear death then you are making no progress.
Advancement in spiritual life does not depend on any kind of previous education or qualiﬁcation. The method itself is so pure that by simply engaging in it one becomes pure.
Bhagavad Gita 9.2,
To chant the holy name and dance in ecstasy is so easy and sublime that one can achieve all the benefits of spiritual life simply by following this process.
Srimad Bhagavatam 6.2.11,
Cleanliness is essential for making advancement in spiritual life. There are two kinds of cleanliness: external and internal. External cleanliness means taking a bath, but for internal cleanliness one has to think of Krishna always and chant Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. This process cleans the accumulated dust of past karma from the mind.
Bhagavad Gita 13.8-12,
Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare. In Kali-yuga, if this Vedic maha-mantra is chanted regularly and heard regularly by the devotional process of shravanam kirtanam, it will purify all societies, and thus humanity will be happy both materially and spiritually.
Srimad Bhagavatam 4.18.14,
If someone is shaving with a straight edge razor and they are a little careless, they can easily cut themselves. So, spiritual life is like a razor’s edge: just that it takes a little bit of bodily identification, a little bit of mental concoction and we may get off the track. Maybe in a future life we will get a chance. Nothing is lost is in this endeavour.
